Get DLL as part of a build, instead of on every run of setup.py

[pradyunsg]

This would make the pip installation faster, since the getDLLs calls would not happen when pip calls setup.py egg_info.

pysdl2-dll/setup.py

Lines 10 to 14 in 0c1bb02

	# Get the necessary SDL2 DLLs for the platform
	override = os.getenv('SDL2DLL_PLATFORM')
	platform = get_platform() if not override else override
	getDLLs(platform)

This should mostly be a matter of moving this logic to happen in the bdist_wheel or build command from setuptools, instead of happening at the top level in setup.py.

I didn't know this was possible, thanks! Could you point me to the relevant setuptools documentation? I tried searching for it myself, but the API documentation for build and bdist_wheel seem to come up blank: https://setuptools.pypa.io/en/latest/deprecated/distutils/apiref.html#module-distutils.command.build

On the note of setup.py/building, the build system should be using pyproject.toml nowadays.

I am not sure if the build system will be up for completely migrating your current setup.py to it, but it should at least be mostly possible.
