Release of LoFreq version 2.1.2

A long overdue release with many, many smaller bug fixes and improvements (almost would have justified a version bump to 2.2). Main focus were the indel and somatic calling routines. By far the biggest visible change is that we got rid of the consensus variants (CONSVAR) concept and now assign qualities to all variants (in the past CONSVARs could not be filtered based on quality)
