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.

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.

Summary:
Available at login.getgrist.com/signup, the new sign-up page
includes similar options available on the hosted Cognito sign-up
page, such as support for registering with Google. All previous
redirects to Cognito for sign-up should now redirect to the new
Grist sign-up page.
Login is still handled with the hosted Cognito login page, and there
is a link to go there from the new sign-up page.
Test Plan: Browser, project and server tests.

Summary:
The user profile dialog is now a separate page, in preparation
for upcoming work to enable MFA. This commit also contains
some MFA changes, but the UI is currently disabled and the
implementation is limited to software tokens (TOTP) only.
Test Plan:
Updated browser tests for new profile page. Tests for MFAConfig
and CognitoClient will be added in a later diff, once the UI is enabled.

Summary:
With this change, if a comment is added to an ACL formula, then that comment will be offered to the user if access is denied and that rule could potentially have granted access.
The code is factored so that when access is permitted, or when partially visible tables are being filtered, there is little overhead. Comments are gathered only when an explicit denial of access.
Test Plan: added tests, updated tests

Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
