Improve disassembled code

[hsnaves]

Hi,

First of all, thank you very much for this great project! I learned so much about the Alto by reading the source code in this repository.

I noticed that the annotated code in https://github.com/livingcomputermuseum/ContrAlto/blob/master/Contralto/Disassembly/altocode24.mu has some missing addresses for some instructions. I recently wrote a microcode assembler for the Alto (see https://github.com/hsnaves/palo), and maybe we can use it to annotate the remaining addresses.

By the way, how do you originally annotate the code?

Thanks,
