[BUG] Incorrect did matcher regex

[stephhuynh18]

Current Behavior

Did matcher regex used in the parse function (https://github.com/decentralized-identity/did-resolver/blob/master/src/resolver.ts#L166) uses an incorrect regex according to the specification (https://www.w3.org/TR/did-core/#did-syntax). Specifically:

• method should not include capitals which it currently does
• method_id should allow for sequential colons (ex. did:method::id)
• % can only be followed by two hex digits (ex. did:method:%1p is invalid while did:method:%1f is valid)

Expected Behavior

The matcher regex should conform to the did specification.

Failure Information

parse('did:CAPITALS:id')

{
  did: 'did:CAPITALS:id',
  method: 'CAPITALS',
  id: 'id',
  didUrl: 'did:CAPITALS:id'
}

Steps to Reproduce

1. Invoke parse with a did that follows the specification and parse will return null OR with an invalid did and parse will return a ParsedDid
