Add old German radars `deflg` and `desna` to OPERA radar database

[peterdesmet]

In BALTRAD, there were data submitted for the following two radars that are not listed in the OPERA radar database:

• deflg (data until 2018)
• desna (data until 2019)

I don't have more info about these radars, except for what I can find in the vp data:

deflg

source: NOD:deflg,WMO:10908,RAD:DL81,PLC:Feldberg
interval: 200
levels: 20
lat: 47.8736
lon: 8.0036
height: 1516
minheight: 0
maxheight: 4000

desna

source: NOD:desna,WMO:10873,RAD:DL82,PLC:Schnaupping
interval: 200
levels: 20
lat: 48.1747
lon: 12.1018
height: 677
minheight: 0
maxheight: 4000

deflg is old name for defbg

deflg

• Data: 2016-2018
• Coordinates: 47.8736, 8.0036 (in file deflg_vpts_20180108.csv)
• Source: NOD:deflg,WMO:10908,RAD:DL81,PLC:Feldberg (in file deflg_vp_20180108T1445Z_0x5.h5)
• Radar metadata: not listed

defbg

• Data: 2019-2023
• Coordinates: 47.87361, 8.00361 (in file defbg_vpts_20190910.csv)
• Source: WMO:10908,NOD:defbg (in file defbg_vp_20190910T080000Z_0xb.h5)
• Radar metadata: https://aloftdata.eu/radars/#defbg

Conclusion

Both radars have the same coordinates and WMO name: deflg can be a considered an older synonym of defbg. The only odd thing is that the recent name defbg has 2015-2018 data in UVA_VPTS: maybe it was updated to align with the new name.
