Support DID resolution parameters?

[andrewwhitehead]

In order to restrict the resolution of the associated DID, it may be useful to support DID resolution parameters in the _did subdomain URI record. This would change the URI field from a DID to a DID-URL, meaning that a resolver would be expected to strip off any parameters to discover the base DID. As a motivating example, the following syntax could be used to attach a hashlink to the DID-URL and provide some integrity protection over the resulting document:

did:web:domain.example?hl={hash}

For use with did:tdw, it would also be beneficial to define a minimum version ID (and hash) to resolve, such that the log file can't be rolled back past a certain point without breaking the resolution process.
