Add S3 File Provider

[NolanTrem]

WIP: Will be released with v3.6.0

Adds support for S3 as a file provider as a configurable alternative to the existing Postgres Large Objects table which is used to store files.

Outstanding issues/work:

• Test with additional S3 providers
• Documentation, examples
• S3 ingestion via SDK
• MinIO Docker
• Supabase is not working with certain file types.

MinIO:

Supabase:

See: supabase/storage#639
The following errors are raised when using Supabase buckets, but not other S3 compatible buckets.

File Type	Error Reason

A shot in the dark here, but should this be "supabase"?

I think we'll keep this to s3, since it should support any s3 compatible solution (not just Supabase).
