Hello pespin, Jenkins Builder, 

I'd like you to reexamine a change. Please visit

    https://gerrit.osmocom.org/c/osmo-gsm-tester/+/18637

to look at the new patch set (#2).

enb,ms: refactor base_rate selection for ZMQ

Use tailored sample rate only use for 6, 50 and 75 PRB. For all other bandwidths,
we use the full LTE rate and downsample.
With 5.76e6 as base sample rate, for example, we had some issue during the tests like:

[zmq] Error: tx time is 0.178 ms in the past (7833600 < 7835648)
[zmq] Error: tx time is 0.011 ms in the past (7835520 < 7835648)

Using a higher sample rate seems to work better.
