feat(config): add support for v2 asc json

This commit adds support for a v2 format of the application specific
configuration file, centralizing on JSON to maximize the knowledge
crossover for people already familiar with the types used in
komorebi.json.

The biggest difference besides the format change is that matchers must
be used explicitly for every kind of rule, rather than being able to
specify options on a default rule. This is a bit more verbose, but
ultimately allows for significantly more flexibility.
