Example for Determining Optimal BlockReadSize

[cjsha]

The docs suggest the user can use MemoryMonitorData to determine an optimal BlockReadSize which seems to be set by the ReadSize property of StartAcquisition. We should write a tutorial how they can use MemoryMonitorData to do that.

According its remarks, BlockWriteSize isn't as critical as BlockReadSize, but it would probably be worth mentioning it as well in the same tutorial, as well as MaxReadFrameSize and MaxWriteFrameSize.

This should be a tutorial, I agree. It should document an updated version of the LatencyTest workflow in the old docs https://open-ephys.github.io/onix-docs/Software%20Guide/Bonsai.ONIX/Bonsai%20Examples/LatencyTest.html
