Show cycles for mnemonics

Feature Request

It would be very useful to show the used cycles for each mnemonic. Maybe also an option to summarize cycles on selected rows (?) When i hover over a mnemonic there is already a tooltip describing the mnemonic available (using placeholder lorem ipsum though... 😉 ) Anyway i think the used cycles should be displayed (optionally) on each line right after the instruction (perphaps in a similiar manner as gitlens is doing it for the last commit for each line in dark grey or as a separate fixed column between line number and code (?))

I don't know if its nececessary (because a static mnemonic->cycles table as reference internally might also do it), but maybe you can adopt the 6502 CPU Emulator for this from https://github.com/rosc77/vs64 ?
