Description
The x509-cert builder currently only supports the RFC 5280 approach of using SHA-1.
https://github.com/RustCrypto/formats/blob/x509-cert/v0.3.0-rc.4/x509-cert/src/macros.rs#L134-L135
RFC 7093 extends this to allow additional methods.

Research direction
Start with x509-cert/src/macros.rs at the referenced lines and read RFC 7093 to identify the additional SubjectKeyIdentifier methods. Trace how the x509-cert builder currently selects SHA-1, then support the RFC 7093 alternatives and verify that the builder handles each supported method.
