SET_CERT: ResetRequired handling

[rw8896]

It seems that the following behaviors haven't been implemented in libspdm yet.
If that's the case, is there any existing issue or plan to fix it?

"If the device temporarily cannot write to a slot, including in a case when it receives overlapping SET_CERTIFICATE requests from different Requesters, then the device shall respond with anErrorCode=Busy response.

When a reset is required for a pending previous SET_CERTIFICATE request and the device receives a GET_CERTIFICATE request for a pending slot or a GET_DIGESTS request, the device shall respond with an ErrorCode=ResetRequired response."
