Quiet errors from missing RCT payload, which is expected for MC

[mulhearn]

For Stage-1 (2015) RCT readout capability was added, and an unpacker, but an MC emulation for this payload was never developed. This PR quiets errors from the resulting oft-encountered situation that the RCT payload is missing.

This is of little interest to anyone!
