Daira Hopwood 4821afe9ba Add a clarification in \crossref{txnconsensus} that after Heartwood and before Canopy activation, 
Sapling outputs of a coinbase transaction MUST have note plaintext lead byte equal to 0x01.
This was implied by the existing rule that such outputs MUST decrypt successfully with an
all-zero outgoing viewing key.
