Title: Make Mdtags handle '=' and 'X' cigar operators

I'm getting some crashes downstream in Guacamole related to reconstructing a reference sequence from cigar+md tag strings where the cigar contains the '=' and 'X' operators; I assume they are currently not handled because it hasn't been necessary, as opposed to due to a conscious decision not to support them, so this adds support for them.
