rust-lib-reference-genome 0.3.0

# This workflow reads the version from Cargo.toml. If a GitHub Release for that
# version does not exist, it creates the tag, a notes-only GitHub Release, and
# publishes the crate to crates.io.
# Steps:
# - Get the version from the Cargo.toml file
# - Check if the release already exists
# - If not:
#   - Call the create-lib-release workflow (tests, tag, changelog GitHub Release)
#   - Publish to crates.io
# Errors:
# - If no version is found in the Cargo.toml file, the workflow will fail
# - If CHANGELOG.md has no section for the version, create-lib-release will fail
# - If the create-lib-release workflow fails, the workflow will fail
# Maintenance:
# - Update the Rust version here and in create-lib-release / crates.io publish to match
