Fix rendering base-level alignments on synteny visualizations, especially in inverted regions

[cmdcolin]

• Gets rid of the awkward flipInsDel variable on the synteny feature, instead, properly fixing the CIGAR string in the adapter
• Gets rid of the awkward revCigar variable on the synteny feature, instead, properly fixing the CIGAR string in the adapter
• Adds mutated-volvox example with some CIGARs and indels and inversions. I visually verify all the indels inside of inversions and add unit tests to help catch this
