Refactor dis module to separate instructions creation from formatting

[iritkatriel]

The dis module is not very flexible, because the formatting and instruction creation are all entangled with one another. I will refactor it so that we are able to feed an instruction sequence to a formatter, or to plug in a different formatter into dis functions.

Nice. This should aid testing and would allow an IDE, for instance, to more easily put dis output in a GUI panel. I might think about putting a tkinter option in dis itself.

Triage: the linked PRs are merged, can this be closed?

There will probably be more in this space, but I can reopen if so.
