Optional self in patterns, no configuration option required

[bnorick]

Here's what I envisioned, no additional configuration option is required and both selfless and selfish patterns are supported.

Thoughts?

@bnorick Thanks for submitting the PR for review! At this time I'm not planning to merge it. It's more code than I'd like to maintain for what amounts to saving a a few characters.

I really appreciate the other contributions you've made to this project! :v:

I guess I'll have to code golf it then 🤣

[bnorick]

It seems pretty minimal already, to be honest, and it doesn't seem to me that it would need any maintenance. If you won't accept this sort of PR because you don't think it matters then that's fine, just let me know.

But just look at "/path/to/root/{key}/{subkey}.toml" vs"/path/to/root/{self.key}/{self.subkey}.toml" :rofl:

I don't think avoiding the need for the self. prefix is a big concern right now, but thanks for the proposal!
