Replace aws with S3mini for more storage providers

[good-lly]

Hi! Amazing project!

I think switching for S3mini could be a great fit - https://github.com/good-lly/s3mini

Tested on multiple platforms and with improved speed

Agreed. Would love to be able to use any s3-compatible storage layer for example Wasabi or Mega S4.
