Large plain/text files returned as gzip and library doesn't handle this case

[grunichev]

python --version Python 3.6.1

smartfile==2.19

Example from documentation:

>>> import shutil
>>> from smartfile import BasicClient
>>> api = BasicClient()
>>> f = api.get('/path/data/', 'small.txt')
>>> with open('small.txt', 'wb') as o:
>>>     # f.getheaders().get('Content-Encoding') 
>>>     shutil.copyfileobj(f, o)

works fine with small files, but when file is large (I tested 100Mb text file) f.getheaders().get('Content-Encoding') returns gzip and instead of expected source text file gzip content is downloaded and saved to file.

It can be handled with:

        if f.getheaders().get('Content-Encoding') == 'gzip':
            o.write(gzip.decompress(f.read()))
        else:
            shutil.copyfileobj(f, o)

but ideally I think library should handle this case. Or, at least, docs have to be updated and mention this possible issue.
