Description
It is not possible to specify the value for k allowing the usage of https://tools.ietf.org/html/rfc6979
This limits the ability to use libcrypto ECC operations in a number of ways.
OpenSSL::PKey::EC#dsa_sign_asn1 should take an optional precomputed K value as those APIs exist in OpenSSL

Research direction
Start at OpenSSL::PKey::EC#dsa_sign_asn1 and inspect the corresponding libcrypto ECC signing APIs mentioned in the issue. Determine how an optional precomputed k value should be passed while preserving existing behavior. Done means the method can accept a deterministic k value for RFC6979-style signing.
