[Proposal] Let dev_println use trace logs

[vicsn]

💥 Proposal

Currently, dev_println enabled logs are just printed to stdout (and I assume dev_eprintln to stderr).

We could instead use the trace library, so such logs are easily uniformly retrievable in tmux history and log files.

Is there any downside to doing this?

I would prefer this too. Having dev_println enabled for test_network in snarkOS creates a lot of output that cannot be hidden.

My guess is the reason for a dedicated dev_println function is so the output shows up in frontend tools that do not use logging frameworks, such as leo.
