Veramo Extension Plugin for did:ethr

This Veramo plugin extends the functionality of did-provider-ethr by exposing a new method ethrChangeControllerKey which allows the owner of a did:ethr to change its owner and therefor its controller. Meta transactions are support as well by providing a metaIdentifierKeyId in the options.
