This is bad; we should never assume the intent of the user. I would
rather prompt for these, then bail if the answer is 'no' for any
'requires' modules. Leave it up to the user to make the decision to
update; if they want they will install the latest required modules,
otherwise there isn't much we can do.

If you do any work with UniProt, then Data::Stag *is* required. It is
used by Bio::Annotation::TagTree, the replacement for
Bio::Annotation::StructuredValue (this has been the case for a couple
years now I believe). The Data::Stag update is small but required as
well, BTW, unless you want warnings popping up.
