apocelipes fd985d23dc crypto/x509,math/rand/v2: implement the encoding.(Binary|Text)Appender
Implement the encoding.(Binary|Text)Appender interfaces for "x509.OID".

Implement the encoding.BinaryAppender interface for "rand/v2.PCG" and "rand/v2.ChaCha8".

"rand/v2.ChaCha8.MarshalBinary" alse gains some performance benefits:
