TODO list:
    1 special segment / text_prof
        * added special segment
        * deleted text_prof (only needed for a command line option we don't need to support)
        * ignored mem_dump_prof
    2 interrupts
        * added interrupt defines to image.h
        * these are used in spimbot code (maybe move them to mmio.h later?)
    3 LAST_REAL_EXCEPT / last_exception_addr
        * ported both with no changes
        * not too sure what LAST_REAL_EXCEPT is doing if I'm being honest but just seems to set EPC even if the exception is unrecognized
    4 RUN_SPIM && RUN_PROGRAM (incl steps game loop) (incl setting PC)
        * changed run_spim -> step_spim to be more clear (run.cpp)
        * changed run_program -> run_spim_program, run_spimbot_program (spim-utils.cpp)

    >> run lots of tests
        * all pass with 1 context
        * all pass with 4 contexts (!)

    5 trans_buffer (?)
        * to make things simple, deleted all references to this by clearing all built-in mmio functions
        * spim-new is now equal to qtspimbot in this regard
    6 breakpoint (per context?)

    >> run breakpoint tests

    7 MMIO functions
    8 other spimbot hooks
    9 misc (#fixme)

    >> run lots of tests
    >> merge into new spimbot
