Compress sourcemaps before uploading to server

[kaatt]

Problem Statement

I'm on a bad internet connection and it takes ages to upload files to the server using releases [..] files [VERSION] upload-sourcemaps

Solution Brainstorm

Most source maps can have a 5x reduction in size when gzipped.

Can you implement this functionality so that sentry-cli compresses files in-memory before uploading them to the server?

As mentioned above, note that sentry-cli requires Sentry to handle uncompression first before we implement it there, so this is not sentry-cli issue "just yet".

Putting to Backlog per your comment @kamilogorek, if wrong please adjust. 🙏

Closing in favor of getsentry/sentry-cli#2181.

Please not, however, we already perform some compression when uploading via chunked uploading (which should be the default with Sentry SaaS and all modern versions of self-hosted Sentry). I believe the compression is performed on individual chunks, rather than the entire file.
