These reads are ok according to SAM/BAM spec, but Manta can't work with them

We have tested this change on 100 cases and all output was identical to the original workaround using awk to filter alignments before calling manta. |

These reads are ok according to SAM/BAM spec, but Manta can't work with them.
This fixes issue #137 "Manta crashes on input files realigned with ABRA #137"
as well as issue #184 "Unclear how to deal with CIGAR strings with InDels at the end of reads"
The fix is to remove offending alignments in the bam streamer instead of throwing an exception much later in the code. This has the same effect as pre-filtering the alignments using awk (as described in issue 184), but it is much faster.
