Problem with Cryptopia ticker()

[iuvbio]

Hi, I get a JSONDecodeError when I call the ticker() method of the Cryptopia interface:

Traceback (most recent call last):

simplejson.errors.JSONDecodeError: Expecting value: line 1 column 4 (char 3)

I think it's because the BOM Header that is mentioned in the docstring of the CryptopiaREST _query is not removed correctly.

In the dev branch I fixed the cryptopia API, see PR here: #182
