Old version installed when using pip?

[brorfred]

Hi!

I have a problem when installing mbutil via pip. When running disk_to_mbtiles compression=True, I get the following error:

`/home/bror/.local/lib/python3.6/site-packages/mbutil/util.py in disk_to_mbtiles(directory_path, mbtiles_file, **kwargs)
257
258 if kwargs.get('compression', False):
--> 259 compression_prepare(cur)
260 compression_do(cur, con, 256, silent)
261 compression_finalize(cur)

TypeError: compression_prepare() missing 1 required positional argument: 'silent'
`

This issue seems to be fixed on github though. Just wanted to make sure that this a pre-release code and not a caching problem at pypi...

pip install mbtiles-zyx can be used by those running into issues with the original mbtiles not being up-to-date with the GitHub version.
