This allows us to set the DAC from SoapySDR. Though measuring and calibrating from the host is super noisy. Ultimately we will want to have the latch set by PPS. Soeren noted that the untuned VCTCXO should be more than precise enough for our needs. Using Base.Libc.systemsleep we measured about a 0.2% error, far less than other readings we have taken. There is more infrastructure here we will eventually want, so this is likely a reasonable intermediate merge while we track down other issues.
