Add an option to aminoAcidProperties to use region definitions

[ssnn]

It can be useful to get the amino acid properties for the different regions

[Jason Vander Heiden]

The problem I foresee with this is that RegionDefinitions are part of shazam, and shazam depends on alakazam, not vice versa. So we'd have to move RegionDefinition into alakazam.

Hrm. alakazam::extractVRegion can accomplish this task already, so it would probably be better to have an argument to pass the sequences through extractVRegion before calculation instead of using RegionDefinition objects.

Issue #28 is relevant.
