alimask crashes when given bounds that are outside the range of the alignment

[npcarter]

Alimask crashes if asked to mask an alignment in a region that's outside the range of the alignment.

Example, on an alignment from Pfam-seed that has width 49:

npcarter@Mac-mini src % ./alimask --alirange 10..100 ~/known-good/test-align ~/test-results/masked

alimask :: appending modelmask line to a multiple sequence alignments
