Change simpleaf protocol name from 10xv4 to 10xv4-3p

[milos7250]

At this moment, running the pipeline on samples with 10XV4 protocol and simpleaf aligner fails. As can be seen in the list of supported chemistries in simpleaf, the chemistry 10xv4 does not exist, they only have 10xv4-3p available. This issue was not flagged in tests, as the test dataset is only using 10xv2 protocol.

This PR only changes the protocol name for this particular chemistry, but perhaps the whole list should be changed to more closely follow the list of available chemistries of simpleaf?
