Bug: partial unzips result in failing functionality

[tbeertje21]

I only need the Brussels part of best-full-latest.zip. So, I only extract the Brussels' files from the zip (avoids a lot of waste of disk space)...
So, I'd expect this to work as per targetting functionality as per --help:
... --region {belgium,brussels,flanders,wallonia}

However (reproduceable):
...>python converter.py --verbose --region brussels . bru.csv
2019-11-01 18:45:28,477 - main : ERROR - File for data of type ['FlandersAddress', 'FlandersMunicipality', 'FlandersPostalinfo', 'FlandersStreetname', 'WalloniaAddress', 'WalloniaMunicipality', 'Wallon
iaPartOfMunicipality', 'WalloniaPostalinfo', 'WalloniaStreetname'] was not found in the input folder

To my understanding, the check in converter.py line 56 keys = FILE_KEYS is needlessly strict: it Must only check required files. This seems a bug to me.

Bypass for me: in constants.py, removed lines so that FILE_KEYS = [
'BrusselsAddress',
'BrusselsMunicipality',
'BrusselsPostalinfo',
'BrusselsStreetname'
]

Not necessarily a bug as the converter script is intended to work in conjunction with the downloader script which extracts all files.

But you have a valid point that extracting all files when you only need a part of it wastes disk space. So I will look into adding a partial extract option and removing the strict file check.
