Support for windows platform about bson-numpy

[behackett]

Since libbson and Numpy already support Windows this shouldn't be difficult in terms of writing code. The existing code likely already works on Windows. The problem is installing on Windows. This likely depends on #22 so users don't have to know or care about library dependencies and compilers or Visual Studio versions.

[behackett]

At the very least we can provide install instructions (once we figure it out ourselves).

bson-numpy has never compiled on Windows. We need to fix these errors:

Hi @peiyaoli. I am closing this as we have discontinued development of BSON-NumPy. PyMongoArrow is now the recommended way to materialize MongoDB query results as NumPy ndarrays as well as tabular formats like Pandas' DataFrames and PyArrow Tables.

Although currently PyMongoArrow is not currently supported on Windows, support for the platform will be added in a future release (tracking ticket - https://jira.mongodb.org/browse/PYTHON-2691). In the meantime, PyMongoArrow wheels are available for download on macOS and Linux on x86_64 architectures from PyPI - https://pypi.org/project/pymongoarrow
