trs80: move bootloader to use sdasz80/sdldz80

I converted the boot loader to SDASZ80, the result assembles neatly into 256 bytes. I included the file so if you like you can check it and place it in github. I didn't change the (complex) makefile, I assembled it with:

sdasz80 -o trs80load.s
sdldz80 -i trs80load.rel
makebin -s 256 trs80load.ihx trs80load.bin
dd if=trs80load.bin of=mydisk.jv3 bs=1 seek=8704 conv=notrunc
