Upload non-github flakes

[Domen Kožar]

Requires a few things to happen:

• auth
• /publish endpoint needs to accept tarball as POST body
• async job to process tarball (evaluate flake, render readme, etc)

render the readme

This won’t be limited to Markdown will it …especially a proprietary fork of the Markdown syntax?

[Matthew Croughan]

The thing currently preventing me from submitting my flakes is the reliance on GitHub features such as actions. Just registering my support for this issue :)

[Paul-Nicolas Madelaine]

I would be interested in adding support for pushing to flakestry from Typhon, if you do end up supporting other authentication methods!
