Allow higher data rates for some front ends.
@jeffrey-kissel requests we allow more than 8 MB/s from some models. In particular, he'd like to be able to open at least 8 but ideally 16 test points on h1iopomc0, a 524kHz model that outputs 2 MB/s per test point.
He would also like to be able to add some number of these channels to the frames.
This plays into the idea of have a network-wide bandwidth control (or at least front end bandwidth control). larger, or non-statically sized DAQ data buffers would be needed.
Number of testpoints on OMC0 is expected to double for O5.
