For "historical reasons" for Eiger data natively written with older filewriter versions we do not directly support the reading of the data but instead perform an in-memory rewrite of the metadata to a more correct NeXus format then work with this.
This has the unfortunate side-effect of needing the data to have write permission in order to read it (because of how HDF5 links work)
Propose:
rewrite the support for legacy Eiger file formats as a LegacyEiger format with no mention of NeXus
eliminate the rewrite solution
Benefit:
users can process data which are in legacy Eiger format and are read-only
the overlap between NeXus and "nearly NeXus" will be reduced, allowing work on making the support for "actual NeXus" to be improved
