This adds a dump function for the ostc3 series computers. This function
dumps the whole external eprom, that contains the dive-headers and the
dive data.

I haven't seen the code for the simulator, but the relevant parts are
that the dive headers are located at:
; 1st: 200000h-2000FFh
; 2nd: 201000h-2010FFh
; 3rd: 202000h-2020FFh
; 100: 264000h-2640FFh
; 256: 2FF000h-2FF0FFh
And in those headers at byte 2 and 5 are the pointers to where in the memory
the actual dive profile are, in little endian.
It shouldn't be too hard to write simulator code for that.
