Add writable fs dot provider; method to receive uploaded files

[infogulch]

Fixes #8

• [x] Create file, make dir
• [ ] Delete files & dirs
• [x] File upload streams files to FS writer.
• [ ] Pending upstream issue https://github.com/hack-pad/hackpadfs/issues/41 . Alternatives:
  • Switch to jarxorg/wfs
  • Don't use abstract FS at all, code against os files directly. I was thinking it would be nice to keep the same provider and allow users to override the target with alternative implementations (nfs, s3, sqlite fs, etc), but maybe this is too much of a stretch.
• [ ] Add more tests, set up test runner to reset uploaded files

hey @infogulch and @ taophp

I know hackpadfs, but its not really that stable and worked out.

https://github.com/tractordev/toolkit-go/tree/main/engine/fs is much h better,.

The tractor dev team were originally using Hackpadfs, and also hit problems and so they then build https://github.com/tractordev/toolkit-go

So it might be worth looking at https://github.com/tractordev/toolkit-go
