Subject: [PATCH] typedunits: add build-typedunits.yml for riscv64 wheels

Builds the TypedUnits Cython extension (import name tunits, PyPI name
typedunits) from an upstream checkout, writing version/version.txt the
same way upstream's own release workflow does so the wheel version
matches the git tag.
