v7.7.1

• Use cargo metadata crate to replace cargo root finding logic
• Update insta test helper to maybe help on the cross-platform front (#170)
• Include module path in debug logging
• Update other deps
• Remove dependence on an empty tests/touchdata directory for tests to pass
• Run tests in CI again (on Linux)
• Be a little more flexible on the version of watchexec (not quite semver yet!)
