Issue:
Allow % char in DID
I wanted to add support for url encoded port numbers in the did:web resolver and use pyDID for DID validation.
pyDID does currently not allow the % char in the method specific id. 
The DID core spec has been updated to allow % char. See https://github.com/w3c/did-core/pull/703
