We optimized note_commitment evaluation by sharing a portion of the hash evaluation between ZEC and ZSA.
1. message_common_prefix = a || b || c || d || e || f || g
2. message_suffix_zec = h_zec
3. message_suffix_zsa = h_zsa || i || j
4. Q = if (is_native_asset == 0) {Q_ZSA} else {Q_ZEC}
5. common_hash = hash(Q, message_common_prefix) // this part is shared
6. hash_point_zec = hash(common_hash, message_suffix_zec)
7. hash_point_zsa = hash(common_hash, message_suffix_zsa)
8. hash_point = if (is_native_asset == 0) {hash_point_zsa} else {hash_point_zec}
