Build and publish wheels for Windows

[chaitan94]

Need to fix all the errors and warnings when compiling on the MSVC platform.

Some sample errors and warnings:

  ./source\io\Deserializer.cpp(235): warning C4267: 'initializing': conversion from 'size_t' to 'int', possible loss of data
  ./source\io\Deserializer.cpp(254): error C2908: explicit specialization; 'T Deserializer<T>::nextValue(void)' has already been instantiated

Fixed in ee6ba96f0b243311ddd1f651065e11f0e88d5997, 1a311828c0982d2dfdd9e7a6b95b9f890b9a4500 and 1add9c16e812ab31873e58d1a896d80c5b4cf079, GitHub action was added in 330b655b4073f876a3df30eaf062d6a67819866e.

The issue was mostly the following things are to be considered when compiling with MSVC:

1. We need to use _mkgmtime in place of timegm
2. We need to import <windows.h> for min and max functions to work
3. When doing put_time, %z does not work as expected, hence best avoid it
4. Fix DLL importing logic for Windows Python 3.8+

Additional notes for 4: For Python versions 3.8+, DLL importing mechanism changed significantly (Refer: https://docs.python.org/3/whatsnew/3.8.html#bpo-36085-whatsnew). Hence we need additional logic within the codebase to call os.add_dll_directory with appropriate path from which the DLLs can be loaded, which in our case is the geos_c.dll. Accordingly, I had to find a way to include python code to run along with the existing C++ extension module which is built with pybind11. So some refactoring has been done for that in 1add9c16e812ab31873e58d1a896d80c5b4cf079.
