Investigate conventional data types/subtypes

[EdwardSafford-NOAA]

The ConMon update, #28, has revealed several missing types/subtypes. The specific data classes/types/subtypes are:

q130_00 q132_00 q135_00 q182_00
uv242_00 uv243_00 uv243_55 uv243_56 uv245_257 uv246_257 uv246_270 uv248_00 uv250_00
uv251_00 uv252_00 uv253_00 uv253_55

It's not clear at this moment if that is to be expected or indicates a problem. That question will be investigated as the first item in this issue.

Secondly, the list of expected data classes/types/subtypes is hard-coded in the ConMon plot scripts. The expected list of items to process should be maintained in a fix file, along the lines of the satype files that the RadMon and OznMon use to supply the expected data sources. Replace the hard-coded list with an external list.
