Title: samtools merge to trace transformations applied to @RG IDs

Adds a `-t ` option for `samtools merge` to create a tab-delimited text file in the format;
````
bam_filename @RG_ID Transformed_@RG_ID
````
This allows users to keep track of a particular read group ID through the merge process via a simple lookup file.
