7e50467396 (core) tweak handler for aborted connections to work on modern node
Summary:
It became hard to detect aborted connections in node 16.
In node 14, req.on('close', ...) did the job. Thid diff adds a
work-around, until a better way is discovered or added.
Aborting a req will typically lead to 'close' being called
on the response, without writableFinished being set.

Test Plan:
existing DocApiForwarder test passes; manually
checking on various node versions.

e10067ff78 (core) Rearrange ExportXLSX code and fix ExportsAccessRules test that became flaky
Summary:
- Move makeXLSX* methods to workerExporter file to avoid the risk of creating a piscina worker pool from a thread.
- Increase request timeout in ExportsAccessRules test that started failing occasionally

Test Plan: Test should succeed more reliably

d191859be7 (core) For exporting XLSX, do it memory-efficiently in a worker thread.
Summary:
- Excel exports were awfully memory-inefficient, causing occasional docWorker
  crashes. The fix is to use the "streaming writer" option of ExcelJS
  https://github.com/exceljs/exceljs#streaming-xlsx-writercontents. (Empirically
  on one example, max memory went down from 3G to 100M)
- It's also CPU intensive and synchronous, and can block node for tens of
  seconds. The fix is to use a worker-thread. This diff uses "piscina" library
  for a pool of threads.
- Additionally, adds ProcessMonitor that logs memory and cpu usage,
  particularly when those change significantly.
- Also introduces request cancellation, so that a long download cancelled by
  the user will cancel the work being done in the worker thread.

Test Plan:
Updated previous export tests; memory and CPU performance tested
manually by watching output of ProcessMonitor.

Difference visible in these log excerpts:

Before (total time to serve request 22 sec):
```
Telemetry processMonitor heapUsedMB=2187, heapTotalMB=2234, cpuAverage=1.13, intervalMs=17911
Telemetry processMonitor heapUsedMB=2188, heapTotalMB=2234, cpuAverage=0.66, intervalMs=5005
Telemetry processMonitor heapUsedMB=2188, heapTotalMB=2234, cpuAverage=0, intervalMs=5005
Telemetry processMonitor heapUsedMB=71, heapTotalMB=75, cpuAverage=0.13, intervalMs=5002
```
After (total time to server request 18 sec):
```
Telemetry processMonitor heapUsedMB=109, heapTotalMB=144, cpuAverage=0.5, intervalMs=5001
Telemetry processMonitor heapUsedMB=109, heapTotalMB=144, cpuAverage=1.39, intervalMs=5002
Telemetry processMonitor heapUsedMB=94, heapTotalMB=131, cpuAverage=1.13, intervalMs=5000
Telemetry processMonitor heapUsedMB=94, heapTotalMB=131, cpuAverage=1.35, intervalMs=5001
```
Note in "Before" that heapTotalMB goes up to 2GB in the first case, and "intervalMs" of 17 seconds indicates that node was unresponsive for that long. In the second case, heapTotalMB stays low, and the main thread remains responsive the whole time.

65013331a3 (core) Fix imports into reference columns, and support two ways to import Numeric as a reference.
Summary:
- When importing into a Ref column, use lookupOne() formula for correct previews.
- When selecting columns to import into a Ref column, now a Numeric column like
  'Order' will produce two options: "Order" and "Order (as row ID)".
- Fixes exports to correct the formatting of visible columns. This addresses multiple bugs:
  1. Formatting wasn't used, e.g. a Ref showing a custom-formatted date was still presented as YYYY-MM-DD in CSVs.
  2. Ref showing a Numeric column was formatted as if a row ID (e.g. `Table1[1.5]`), which is very wrong.
- If importing into a table that doesn't have a primary view, don't switch page after import.

Refactorings:
- Generalize GenImporterView to be usable in more cases; removed near-duplicated logic from node side
- Some other refactoring in importing code.
- Fix field/column option selection in ValueParser
- Add NUM() helper to turn integer-valued floats into ints, useful for "as row ID" lookups.

Test Plan: Added test cases for imports into reference columns, updated Exports test fixtures.

51ff72c15e (core) Faster builds all around.
Summary:
Building:
- Builds no longer wait for tsc for either client, server, or test targets. All use esbuild which is very fast.
- Build still runs tsc, but only to report errors. This may be turned off with `SKIP_TSC=1` env var.
- Grist-core continues to build using tsc.
- Esbuild requires ES6 module semantics. Typescript's esModuleInterop is turned
  on, so that tsc accepts and enforces correct usage.
- Client-side code is watched and bundled by webpack as before (using esbuild-loader)

Code changes:
- Imports must now follow ES6 semantics: `import * as X from ...` produces a
  module object; to import functions or class instances, use `import X from ...`.
- Everything is now built with isolatedModules flag. Some exports were updated for it.

Packages:
- Upgraded browserify dependency, and related packages (used for the distribution-building step).
- Building the distribution now uses esbuild's minification. babel-minify is no longer used.

Test Plan: Should have no behavior changes, existing tests should pass, and docker image should build too.

08295a696b (core) Export to Excel and Send to drive
Summary:
Implementing export to excel and send to Google Drive feature.

As part of this feature few things were implemented:
- Server side google authentication exposed on url: (docs, docs-s, or localhost:8080)/auth/google
- Exporting grist documents as an excel file (xlsx)
- Storing exported grist document (in excel format) in Google Drive as a spreadsheet document.

Server side google authentication requires one new environmental variables
- GOOGLE_CLIENT_SECRET (required) used by authentication handler

Test Plan: Browser tests for exporting to excel.
