Feature request: open buffer in chosen project

[hardenedapple]

I would like to open a buffer restricted to a given project (as the way to "jump" to that project -- once I've changed dir to that project root the builtin.buffers picker works just fine).

I copy-pasted and tweaked to get the below which appears to work, but not opening as a pull request since I have very little idea what is going on and don't have a clue what default mappings you would want.
