I have produced cross-platform wheels for plyvel here: https://pypi.o…

…rg/project/plyvel-wheels/#files

- Which fixes this problem: wbolster/plyvel#114 for details on "Symbol not found: __ZTIN7leveldb10ComparatorE" error
- By including a statically linked leveldb v 1.22 in the wheel (for Mac).
- This also saves the user from needing to perform a "brew install leveldb" step and is therefore an essential part of making the SDK a one-click-installation...
