patches jest caching to work around an issue outstanding since 2017

[cache write race condition across processes ](https://github.com/facebook/jest/issues/4444)

- make caching opportunistic: if it works, great, if it fails, c'est la vie!

  - caching should be to improve performance, _not_ a lynchpin

- facilitate complete disable of read and/or write cache

  - because jest writes out cache files even when invoked with `--no-cache`,

    wasting time on I/O for files that won't be used

    

usage

---

```

npx patch-jest-cache {options}

```

- default behavior patches cache reading and writing to only warn on error

- specify `--no-warn-on-errors` to suppress warning messages

- specify `--disable-read-cache` or `--disable-write-cache` to completely

  disable cache read / write

reverting

---

either run `npx patch-jest-cache --revert` or re-install your node_modules, eg

with `npm ci`
