[FEATURE] Add free function alignment_from_cigar.

[smehringer]

When we remove the alignment field from the SAM file, we need to have a replacement in place to get from a CIGAR string, read from file, to an alignment.

I copied over the functionality from IO into a free function in the /alignment module for now.

We should discuss where and how we will provide this feature.
