release: publish to crates.io?

It seems like it wouldn't take too much work to publish most of these crates to crates.io.

There's some odd exceptions for certain github based dependencies:
- `noname`
- `ark-circom`
Are the main ones I'd worry about. I believe `acvm` could be taken from crates.io as well (though it would be worth communicating with Noirlang team.

Easiest move forward would be to feature gate: `noname` and `circom`

Then could publish without those features and add in later as needed and update `default-features` too.

Thoughts?

Start by auditing the crates and their dependencies, focusing on the GitHub-based noname and ark-circom dependencies and the availability of acvm on crates.io. Done means the publishable crates and dependency exceptions are agreed, feature gating and default-features behavior are defined, and the crates can be published with the Noirlang communication considered.
