Ins (APDU instruction codes) enum

Browse Source 
Converts a bag of constant values (`YKPIV_INS_*`) into an enum
representing APDU instruction codes (a.k.a. `ins`).

Among other things, this makes the `Debug` output for `APDU` more human
meaningful, since it can print a text label for the instruction rather
than a code number, which is helpful in trace debugging.
