Add a file writing sink?

[virtuald]

Last year I implemented something that would write images to disk periodically, but only if a USB flash drive was inserted into the roborio. It was pretty useful, and seems like the sort of generic utility that a team would want to have.

I actually hadn't thought of this until now, but maybe it could be implemented as a sink? Something to think about.
