Table 1-01-01, Deprecate observed variable (atmosphere) "Aerological soundings"

[nuneslf]

Initial Request

The following entry exists in the list of observed variables (atmosphere) [http://codes.wmo.int/wmdr/ObservedVariableAtmosphere/_37]:

• "Aerological soundings", which is not a physical variable, I think.
  Therefore, I suggest to removed it (deprecate it) in the next review cycle, noting that the actual variables, available from the Codes Registry, pressure, temperature, water vapor and upper wind should be used for vertical soundings.
  In OSCAR/Surface 36 stations are using such "variable", 30 of these declared as "operational", and around 20 of those are exclusively using "Aerological soundings" and not any of the variables, pressure, temperature, etc.
  The following people have been initially contacted about this: @amilan17, @fstuerzl.

https://github.com/wmo-im/tt-wigosmd/wiki/2022.12.08-TT: @ferrighi will verify

@fstuerzl said that there several records in OSCAR/Surface with this code. (@JohnEyre) It should be replaced with something in an observing methods list. (@gaochen-larc) it's not really a method

As for the branch provided, I can confirm the correct removal of the variable.
