Pickup config from a dataset at some standard location

[yarikoptic]

ATM config should be specified in the command line. Since config quite often dataset specific, such configuration would be stored within the dataset. To not breed various user-specific paths, would be nice to standardize location of such a config (e.g. .bids-validator.cfg) and pick it up by default. It would then require an option to avoid loading it though (e.g. an empty config path in -c?)

Might interact with #279

ha ha - was looking for something like that and found that me-in-the-past already expressed himself. I wish I knew JS enough to not break things, then I would have submitted a PR ;-)

[yarikoptic]

I found myself again here! amazing! So is there a perspective to have this issue addressed (or at least commented on), or I will just keep talking to the past myself here? ;)

This is definitely beyond my JS knowledge, so I don't even have a sense of how great an effort this would be.

@62442katieb Do you happen to have some time to prod at this?

@yarikoptic Do you know any JS developers?

I've added a quick version of this in #891 - documentation for how it works is here. This does introduce a breaking change since relative configuration paths are now interpreted as dataset relative.

THANK YOU @nellh -- skimmed through the code (I have little to no JS knowledge, so it was very superficial) -- looks great to me ;) FWIW, in the use case where I was providing config file, I was using absolute path.
