Working with unknown ROMs, we might know from some other source (or hand-disassembly) that specific locations are actually code, but automatic disassembly doesn't pick them up for some reason (jump tables are a typical problem). It would be useful to have a CLI argument for specifying addresses to perform a final disassembly pass on after we've finished the bulk of the automated work.
Something along the lines of --additional-vectors [<addr1>[,<...>]] would probably be close enough.
