Non-reproducible plots with cudaplot

[llowrey]

I can't get cudaplot to produce reproducible plots. When I use diskplot and the -i arg and I hash the plots (skipping the first 1MB) I get the same hash every time. When I do the same with cudaplot and any -z value, including 0, I get different hashes each time.

I've been trying to figure out why I've been consistently at 3.5-4x effort. Running chia plots check reveals very large numbers of plots dropped due to linepoint compression and quality mismatches. A full 1% are identified as bad. It appears that there is something wrong with my combination of hw/sw and bladebit is churning out a lot of bad plots.
