libdap seems to return DAP2 and DAP3.2 DDX responses in kind of random way.
It may be that the library toggles between DDX versions, or it may be random, or it may be that it gets 'stuck' in one version or the other.
Fix this by changing the behavior so that only DAP3.2 DDX is returned.
Switched to DAP 3.2 DDX in libdap
Modified baselines, saved the DAP2 DDX baselines
Not pushed because I’m waiting on Kent before I push the HDF4/5 tests
