Length of the first M-region
CIGAR character string
If a probe maps exon-exon border region of a transcript,
it does not appear in the Genomic Alignment as a mapping with
CIGAR = "25M", but as mapping with xxM in the beginning of
the CIGAR string, and xxM in the end,
which represents length of the regions mapped
to the left and right exons correspondingly.
cigar2_left function gets length of the left exon mapping,
if CIGAR string has <integer>M in the left-most position.
