SubX: Would be nice to have a --quiet flag to turn off tracing

[akkartik]

It's quiet, I thought? What are you doing when it's noisy?

[tekknolagi]

willow% ./subx run ex2                 
1 entries in the program header, each 20 bytes long
program header at offset 34: type 1
blitting file offsets (54, 66) to addresses (8048054, 8048066)
willow%

Ah, got it. That's not the tracing, just prints using cerr. We can just comment them out, no problem. Wanna do a PR? Just scan for all cerrs in the repo.
