Fix windows package build rel: issues/17

[sigman78]

There are two problems preventing proper windows build:

• need to provide zlib dependency to cmake
• declare dll symbol exports (otherwise ale_c.dll built w/o exports at all, unlike linux .so)

In this PR:

• zlib provided via vcpkg (imo cleaner than using FetchContent logic)
• "export all" option on libs (normally I would DLL_EXPORT only API, but for now this should work as well)
• update github action to build windows bdist (unable to test it in a fork's branch :sad-face:)
• bumper version to 0.1.12

rel #17

I forked your repository and installed multi-agent-ale-py from it. I still get this crash,

I checked and C:\Users\tfn\Documents\proj\.venv\Lib\site-packages\multi_agent_ale_py\ale_c.dll definitely exists.
