Allow times which span over midnight

[klada]

When using the example from the OSM documentation, which has times spanning over midnight, I am getting an exception:

>>> import humanized_opening_hours as hoh
>>> hoh.OHParser("Su-Tu 11:00-01:00, We-Th 11:00-03:00, Fr 11:00-06:00, Sa 11:00-07:00")

    "The field contains a period which spans "
humanized_opening_hours.exceptions.SpanOverMidnight: The field contains a period which spans over midnight, which not yet supported.

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/tmp/osm/lib/python3.7/site-packages/humanized_opening_hours/main.py", line 92, in __init__
    except lark.lexer.UnexpectedInput as e:
AttributeError: module 'lark.lexer' has no attribute 'UnexpectedInput'

It seems like spanning over midnight is already detected, but currently not handled.

I have just tested the Alpha version and it works! Sorry for the noise.

No problem! However, you should be warned that I'm very busy these times, so I cannot guarantee to maintain and improve this module for the long term (sorry)...
