CompoundLocation half done, created as well as sub_features

This modifies the GenBank/EMBL parser and BioSQL loader to create
the CompoundLocation as part of creating the SeqFeature.

NOTE: Need to examine how the location operator (join, order, etc)
should be stored in BioSQL, and what order is used for the location
parts in BioSQL (by the BioPerl loader at least).
Feature location addition (cherry-picked from another branch)
Use CompoundFeatureLocation in GenBank/EMBL output
Label sub_features as obsolete (warnings not very prominent through)
TODO - check how BioPerl stores compound locations in BioSQL
Delagate SeqFeature iter & contains to (compound)location (not using sub_features)
More prominent sub_feature deprecation warnings
Tweaks to GenBank/EMBL code to avoid deprecation warnings
Avoid sub_feature deprecation warnings in tests
Use compound locations not sub_features in BioSQL loader
