Adopt standard software management practices i.e. dependency versioning

[jon-chuang]

It is fairly weird that we are utilising master as the version for downstream dependencies. Perhaps the rationale is that we are not at a release stage of the project yet. Still, it seems wise to start maintaining branches of release versions and in addition to a breakage-prone master? Especially since arkworks is actually being deployed.

We're actually working on getting releases out for all the crates right now haha. We ideally should have everything in place to make a release in a couple days

Ooh awesome!

Basically, or ideally, these repos releases would be on crates.io, and people no longer point to GitHub.

Right, the main blocker is arkworks-rs/std#29, and the corresponding downstream PRs. I plan to merge these ASAP.

Releases are out! Closing this for now, please open new issues if theres any other software development practice's you'd recommend
