TagSort should be able to output BAM

[fredlas]

The usage of TagSort that actually produces a sorted version of the input file (as opposed to just being used to compute metrics) writes a tab-separated ASCII SAM file. TagSort's input is a binary BAM. Since the point of BAM is to save space, and the point of TagSort being C++ is to handle huge data efficiently, it seems likely that someone using sorting feature might prefer BAM output.

It's also possible just converting from SAM to BAM after TagSort is done would work well enough to not justify the additional work this would take.
