Better uploads #587
Description
There's some overlap with https://github.com/gliff-ai/store here, but in general:
- Change Etebase SDK to support dynamic chunks and/or passing chunk sizes in.
- Fix Etebase SDK chunkUpload method to be parallel
- Use PromiseAllSettled rather than Promise.all and make a single failure not fail the entire upload.
- More accurate progress (and change the progress bar)
On Store, we need to investigate the overhead we have on HTTP requests as this currently makes chunking impractical (although could be mitigated with large chunks and parallel uploads)
