Lots of branches from old issues that could be deleted

[WilliamZekaiWang]

notably ones that have closed issues but still have branches:

• iss32
• iss48
• iss49
• iss64

This is for #93, which has been referenced as solved in #101

• iss93

This is branch is for #94 which we can't really do because we haven't located a direct solution to accessing 3seq functions to lock one parent sequence

• iss94

Ones still relevant

• iss100 (RDP refactoring)
• maxchi_chimera (maxchi and chimera refactoring)
• siscan (siscan refactoring, also includes upgma)
