renamed to univax

normalizing credential subjects to common immunizations

adds all known cdc/cvx codes & their metadata
allows to present different credential schema types
improves & simplifies much better credential card rendering
updates to more recent version of https://schema.org#ImmunizationRecord
uses hbs based credential rendering (hard to not to overdo things here :D)

multi credential types | issuer verification

• supports 2 credential formats (still not final, only rudimentary, unchecked creation and still not 100% "original")
• splits credential verification into a hookable split process (ICheckCredentials)
• adds a "root trust" check on the verifier side that tries to find a proof that an issuer itself is allowed to issue credentials of that type. The verifier checks whether it can find a "proof of provider" credential on a proprietary vc registry using a proprietary repository query implementation (out of scope, good for demos)
• providers can register service entries on their did. Issuers can store credentials on the credential registry (unsecure, unencrypted). The registry resolves credentials for verifiers.
• pulls up credential card code to shared frontend (introduces chakra as common dependency)
