Add a CI job to test against the OFM test suite

This should help catch issues earlier - it means if modifications to OFM are needed, this will be flagged early.

It would be nice to keep an OFM branch that's updated with necessary changes for LabThings to work nicely, but this is unlikely to be an automatic thing. For now, I think just being able to check whether the current OFM codebase will work (unmodified) with changes being proposed to LabThings is already helpful.
