This PR removes the orphaned `licenses-binary/LICENSE-machinist.txt` file. ### Why are the changes needed? `org.typelevel:machinist` was a macro dependency of older Spire versions.

No. ### How was this patch tested? N/A. Verified `machinist` is no longer a bundled dependency via the dependency manifest and `dependencyTree`. ### Was this patch authored or co-authored using generative AI tooling?
