new failing test
fixing disassembler byte -> op internal mapping, still have some failing tests around complicated try/catch/finally code indicative of bad branching math though
fix exception block label lookups in disassembler; exception block nesting still wonky in tests
fix exception block call ordering in nested cases
refactor disassembler to use explicit marks even when branching to end of exception blocks, too much juggling to do otherwise
cleanup
fixing try/catch/finally order w.r.t. label marking; some test assertions disabled
restoring tests
