Crash early if sample ID mismatches with ID in VCF header

[Jakob37]

Currently, if you run with a different name from the one in the VCF file, the pipeline crashes far later in the inher_model step, where the Peddy ID (sample ID in the CSV) is matched to the VCF ID.

It would be desirable to crash early, i.e. do a step early on in the pipeline whether the IDs are correctly matching.
