Sodium 1.16.1 Backport 0.1.1-SNAPSHOT+2020-11-30

Regular users want the file ending in 2020-11-30.jar, the rest are for developers only and won't work.

This build contains a workaround for a memory leak identified in GlobalRenderContext a few days ago. Testing has confirmed that this was in fact the leak affecting speedrunners, and that the workaround is effective. Upstream has been made aware of the source of the issue and will likely be refactoring the relevant code more heavily when addressing it. This build also adds a new option for planar fog, which is vanilla behavior when GL_NV_fog_distance is unavailable (such as when using an intel or amd gpu on windows or linux). This option looks worse, and disables fog occlusion meaning it runs worse as well, but can be used to see more chunks, particularly in the nether.
