A truly self-modifying JSR

Gratified to find that my unfinished Electron emulator passed! TBF I cribbed the pseudo-mico-code for the cpu from MAME.

I have tested this with several Commodore +4 emulators: my old Forever+4 and the best plus4emu. Both have successfully passed the test. Commodore emulators need to be very accurate at each CPU cycle because there are a lot of demos and games that depend on this accuracy.

Very good result!
