Merge #63: Configurable API features

c475f48 api: git guard (Nick Johnson)
56683ad api: baseline config (Nick Johnson)
804f63d api: better git state switch (Nick Johnson)
0b1d49b api: Upgrade public-api to v0.50.2 for modern nightly support (Nick Johnson)
8e5eb11 api: Make FeatureConfig configurable via rbmt.toml (Nick Johnson)

Pull request description:

  These changes make the `api` command more robust, been able to use it in the `rust-psbt` project as I explore different ways to break an exported API and see if this detects it. We might just have to drop these custom checks with cargo-semver-checks as discussed in #58, because this is quite the rabbit hole, but figure I'd give it the old college try and learn along the way.

  I think this new `rbmt.toml` config for the api command will be helpful no matter what. It also lets a user opt-in to the semver checking, they have to set a `baseline` in the package config.

  ```toml
  [api]
  # Additional feature combinations to test (beyond no-features and all-features).
  features = [
      ["alloc"]
  ]
  # Optional: Git reference for semver compatibility checking.
  baseline = "v1.0.0"
  ```
