SpruceID OID4VCI Credential Issuance API

SpruceID's OID4VCI (OpenID for Verifiable Credential Issuance) Rust library implements the OpenID4VC credential issuance protocol, enabling credential issuers to deliver W3C Verifiable Credentials to holder wallets. The protocol extends OAuth 2.0 with credential endpoint flows including pre-authorized code flow and authorization code flow. Supported credential formats include JWT-VC, LDP-VC, SD-JWT VC, and ISO/IEC 18013-5 mobile documents (mDL). Used as the issuance layer in the SpruceKit mobile SDK.
