TypeError: '>=' not supported between instances of 'int' and 'datetime.datetime'

Hi again,

while giving the CLI invocation examples some love, I found those examples will croak:

# Acquire monthly data from 2017-01 to 2019-12
wetterdienst dwd observations values --station=1048,4411 --parameter=kl --resolution=monthly --date=2017-01/2019-12

# Acquire annual data for 2019
wetterdienst dwd observations values --station=1048,4411 --parameter=kl --resolution=annual --date=2019

# Acquire annual data from 2010 to 2020
wetterdienst dwd observations values --station=1048,4411 --parameter=kl --resolution=annual --date=2010/2020

Traceback (most recent call last):

With kind regards, Andreas.

P.S.: This is just a note while going through all CLI invocation variants in order to give us a heads up. I might be able to investigate and fix this on my own behalf though.

Will be fixed through #378.
