This is a large change to introduce a proper separation between the creation of the shim directory and the wrapped functions. It is the first stepped to support local wrapping. Notable changes: - Creation of an additional Windows cmd shim if the base name of the executable is not `node`. - Expose object-based API as `spawnWrap.wrapGlobal` - The shim root is now a proper directory, not a "prefix"
The new wrapper API replaces the possibility of setting `args` and `env` with a `wrapper` path and `data` object. It also exposes a new wrapper mode enabling spawning the child process in its own subprocess.
Also rename `applyContextOnGlobal` to `patchInternalsWithContext`
- Use `shimScript` in Node munger (instead of `shimExecutable`). - Wait for the streams to close before ending the TCP sockets used for observable spawns.
The lib was accidentally using `fromArray` instead of `from`.

I'm unsure if anything from this PR is not already merged but I'm closing as I think any changes still required would need to be submitted as separate PR's. |

While working on code coverage, I updated
spawn-wrapto be more reliable, easier to use and provide more features.This PR corresponds to the end result I reached. It is not intended to be merged immediately but should serve as a reference point. I'll break it down to smaller PRs and send them progressively.
Highlights:
The lib no longer requires to globally patch the internals. It's still available but discouraged: you can use an isolated
child_processAPI with wrappers. This allows to run multiple processes concurrently with different wrappers.The API was simplified to easily use a wrapper main module and pass some data to it. I checked all the dependent packages to see how the lib is used: this is basically what it boils down to. You can still pass arbitrary flags or environment variables but it's no longer the default API.
Various refactoring to simplify the code: less mutations, newer syntax, type annotations (catched a few bugs).
