Add option to select certain types of features (nodes/ways/relations)

[RaczeQ]

By default, the QuackOSM loads all features from Nodes, Ways and Relations.
Having the option to specify only some types of features might give some more control over the desired output.

Example:

import quackosm as qosm

qosm.convert_geometry_to_geodataframe(area, osm_feature_types='nwr') # default
qosm.convert_geometry_to_geodataframe(area, osm_feature_types='wr')
qosm.convert_geometry_to_geodataframe(area, osm_feature_types='n')

Final file name might have a suffix with given selected list of types of features (only if it's not default).
