Creating GM db - option to suppress print messages

[shraddhapai]

@philmaweb Can we suppress messages to standard out when GM is creating input PSN?
Ideally there would be a simple progress bar. Also if there is a simple way to speed this step, parallelize if we aren't already doing so, that would speed netDx more. Esp when we have ~2K input features for feature selection & test classification, per train/test split.

Print messages seem to be coming from ProfileToNetworkDriver.
