Function bump

scripts/publish.rs:419–435

Performs a major version bump increment on the semver version `version`. This function will perform a semver-major-version bump on the `version` specified. This is used to calculate the next version of a crate in this repository since we're currently making major version bumps for all our releases. This may end up getting tweaked as we stabilize crates and start doing more minor/patch releases, b

/// releases. This may end up getting tweaked as we stabilize crates and start
