Releasing

These are the steps to create a new release:

Get the latest head you want to create a release from.
Update the version in Cargo.toml to the new version. Without this, the new release will be rejected by crates.io.

Along with this, update the RELEASE_NOTES.md file if it is not complete, up to date, and remove template comments (<!-- ... ->) and empty sections.

Submit a pull request if an update is needed, wait until it is merged, and update the latest head you want to create a release from to get the new merged pull request.
Create a new signed tag using the release notes and a semver compatible version number with a v prefix, for example:
```
git tag -s --cleanup=whitespace -F RELEASE_NOTES.md v0.0.1
```
Push the new tag.
A GitHub action will test the tag and if all goes well it will create a GitHub Release, and upload a new package to crates.io automatically.
Once this is done, reset the RELEASE_NOTES.md with the template:
```
cp .github/RELEASE_NOTES.template.md RELEASE_NOTES.md
```
Commit the new release notes and create a PR (this step should be automated eventually too).
Celebrate!
