smymm 0e33a7b315 Implementation of multi-firmware for PicoGus. 
Flash only one file: pg-multi.uf2 only one time. It contains all firmwares (6 at this moment). You can change between them in DOS: 

New usage for this version:

    pgusinit   /m x [d]  - change card mode to x (1=gus,2=sb,3=mpu,4=tandy,5=cms,6=joy)
               the optional parameter 'd' makes the mode permanent at boot
               (Only if pg-multi.uf2 is flashed)

Examples of use:

    You have default mode as GUS mode on boot, want to change mode to SB, but only temporarily:

    pgusinit /m 2

    You want to change the default (permanent) mode of the card to SB mode, and the next system cold boots / hard resets / power off you want to stay in SB mode without using pgusinit:

   pgusinit /m 2 d
