Use pdbufr to read DWD radar data in bufr format

[gutzbenj]

As suggested by @meteoDaniel this adds pdbufr to the requirements and allows to parse the provided bufr radar data by DWD to a pandas DataFrame. (testing not possible atm as data is not available)

Fixes #364

UPDATE
This won't currently work as of the loose connection between eccodes (the core library) and its python bindings. Differences between versions can lead to an ImportError which is caused by the core library not being found. We should wait for this to be solved to be able to run ordinary checks on bufr files.

UPDATE2
Provision errors of eccodes library can now individually be solved by setting such environmental variable

Hey @gutzbenj I hope you are fine.
I took a look to your first code for handling DWD bufr data. I hope this helps you.
If you want I can write some tests for it ;) Let me know.

[meteoDaniel]

I think more meta data is required to work with radar data.

1. Number of radial bins
2. range
3. azimuth

Take a look at step 11 at https://docs.wradlib.org/en/stable/notebooks/fileio/wradlib_load_DWD_opendata_volumes.html

Thanks for the hint! This was just a first guess as with pdbufr you will have to set everything you want to read in beforehand and can't just read everything that's being found in the file.

Dear @meteoDaniel , could you please check the latest state of the PR? I also couldn't figure out if the information of

• Number of radial bins
• range
• azimuth
  is contained within the bufr files.
