SoLoud fails to detect SDL2 dll when using with VCPKG's SDL2 in debug build

[wutipong]

Expected behavior:

It should detect the SDL2 dll properly.

Actual behavior:

It can't find the SDL2's dll and no sounds is produced. Also a crash when calling stop. This does not affect the release build.

The problem is, VCPKG changes the dll file name to SDL2d.dll when building a Debug project. SoLoud's dll detection code use the file name 'SDL2.dll' to get the dll handle. Since there's no such file it returns in error.

soloud_sdl2_dll.c :

static HMODULE sdl2_openDll()
{
	HMODULE res = LoadLibraryA("SDL2.dll");
        return res;
}

A possible fix would be to try loading the SDL2d.dll when LoadLibraryA() fails.

Steps to reproduce the problem:

• Create a project which use SoLoud and SDL2. The SDL2 here would be VCPKG-based.
• Make a Debug build.
• Run the project

Here's my test project to reproduce the issue. You can clone the project and open the folder in Visual Studio
