Remove or add into algorithms the unthrown errors in specification

[wip-abramson]

This attempts to address #247.

I have added some steps to the DID Resolution Algorithm to throw the FEATURE_NOT_SUPPORTED and INVALID_OPTIONS errors. Additionally I added a paragraph at the end of the algorithm about throwing INTERNAL_ERROR on unexpected errors.

There may be a better way to handle this, wanted to get something in a PR folks could see and argue over.

Wip: I wanted to go back to the PRs, actually

Wip: this one needs a review
… it's about errors
… I've removed a bunch
… but how do we handle where errors defined in the spec weren't used anywhere
… I've added sections to use them
… but I do need reviews
… and we can discuss it if/as needed on a future call
… it is a relatively substantial change

ottomorac: yeah, reviews are really the main thing
… if there are no other concerns, we'll see you next week!
… thanks all
