Refactoring of NSandbox:
- Simplify arguments to NSandbox.spawn. Only half the arguments were used depending on the flavour, adding a layer of confusion.
- Ensure the same environment variables are passed to both flavours of sandbox
- Simplify passing down environment variables.
Implement deterministic mode with libfaketime and a seeded random instance.
- Include static prebuilt libfaketime.so.1, may need another solution in future for other platforms.
Recording pycalls:
- Add script recordDocumentPyCalls.js to open a single document outside of tests.
- Refactor out recordPyCalls.ts to support various uses.
- Add afterEach hook to save all pycalls from server tests under $PYCALLS_DIR
- Make docTools usable without mocha.
- Add useLocalDoc and loadLocalDoc for loading non-fixture documents

Summary:
This is a somewhat experimental change, that will implement permitted parts of an undo if not all parts are permitted. This is in preparation for trigger columns, where it may become common for a change in a record resulting in a change to an automatic change to another that the user cannot edit directly. How to undo such an action is somewhat unclear. One option is to undo the permitted parts, and then the triggers can rerun.
The general case is a bit of a can of worms, and feels adjacent to merging/rebasing etc.
Oh: it would probably be important in general to communicate to the user that an undo was partial, but this diff doesn't do that. It would need some new plumbing.

Summary:
The `_repairWorkspaceGuests` method is slow for workspaces with large numbers of documents. It makes a query that produces a lot of rows. The query itself is tolerable, but TypeORM processing uses enough CPU to be a likely culprit in some production instability. This diff splits the query into two pieces that are logically independent, but which when combined were resulting in the number of rows being the product of the two pieces. Once split, there is also a where clause that can be applied to one of the pieces.
The purpose of the method is to add every user that a document within a workspace is shared with to a "guest" group of the workspace itself. The design of "guest" groups is not ideal, but this diff leaves the design unchanged and is intended only to speed up operation.
Made some small tweaks to the timing of a flakey test, and temporarily recreated the `samples` directory removed in a previous diff (this is currently breaking tests badly on a fresh worker without a `samples` directory lying around)

Summary:
This diff discounts indirect changes for access control purposes. A UserAction that updates a cell A, which in turn causes changes in other dependent cells, will be considered a change to cell A for access control purposes.
The `engine.apply_user_actions` method now returns a `direct` array, with a boolean for each `stored` action, set to `true` if the action is attributed to the user or `false` if it is attributed to the engine. `GranularAccess` ignores actions attributed to the engine when checking for edit rights.
Subtleties:
* Removal of references to a removed row are considered direct changes.
* Doesn't play well with undos as yet. An action that indirectly modifies a cell the user doesn't have rights to may succeed, but it will not be reversible.

Summary:
Previously in {{D1053}} we switched to using BLOB as the "type" for all columns, to prevent SQLite from casting data unexpectedly. This diff now returns to more meaningful types. We apply marshalling to values when being placed in a column where a cast might occur, to inhibit such casting.
The benefit is that Grist documents become easier to interact with via regular database clients/libraries, which often rely on the column type more than a purely SQLite tool would.
On column type conversion, we run all blobs in the column through a decode/encode cycle so if they no longer need to be marshalled they revert to native type. This could be optimized further, it is somewhat brute force.

* Adds a `SELF_HYPERLINK()` python function, with optional keyword arguments to set a label, the page, and link parameters.
* Adds a `UUID()` python function, since using python's uuid.uuidv4 hits a problem accessing /dev/urandom in the sandbox. UUID makes no particular quality claims since it doesn't use an audited implementation. A difficult to guess code is convenient for some use cases that `SELF_HYPERLINK()` enables.
The canonical URL for a document is mutable, but older versions generally forward. So for implementation simplicity the document url is passed it on sandbox creation and remains fixed throughout the lifetime of the sandbox. This could and should be improved in future.
The URL is passed into the sandbox as a `DOC_URL` environment variable.
The code for creating the URL is factored out of `Notifier.ts`. Since the url is a function of the organization as well as the document, some rejiggering is needed to make that information available to DocManager.
On document imports, the new document is registered in the database slightly earlier now, in order to keep the procedure for constructing the URL in different starting conditions more homogeneous.
