Adjust dependency versions

[mdragaschnig]

Hi,

I noted that the current, fixed dependency versions of requests, dateutil and click clash with dependencies for e.g. pandas.

Would it be possible to adjust the Python dependency definitions in setup.py?

Locally I've successfully tested

'requests ~= 2.20', 'python-dateutil ~= 2.7', 'click ~= 7.0'

@medvedev1088 any updates on this please?

Yes it would be possible. If you create a PR I'll review and merge it
