Load config from dprint.json

[stephenh]

Hello! Really enjoying dprint/dprint-node to like ~5-10x speed up some code generation that was going through prettier, so thank you!

Just curious, but AFAICT calling dprint.format is not picking the .dprint.json file that I put into my project's root directory. Should that be happening?

I didn't see any code in dprint-node to do that, but was kinda hoping that dprint internally would just do that; unless maybe it is and I'm missing something?
