draft holddata workflow

[MarkAckert]

This PR is an attempt to detect changes which may require HOLDDATA and flag them via a failing build if there is no matching HOLDDATA updates in the repository's SMP/e service directory.

There's no way we can detect every change which requires HOLDDATA, so ultimately the developers working on features must be responsible for updating HOLDDATA docs. To that end, a small blurb was added to the repo's README which points users to the SMP/e service directory for further instruction.

Tests in another PR showed the workflow works as intended, capturing changes to the SZWE* files and failing when HOLDDATA is absent.
