+- Filesystem watcher reads custom defined file associations

 ### Fixed
 
-- Fixed `#include` merging for when file is merged twice that would normally be `#ifdef` guarded. Please see commit message of [551380a](https://github.com/Strum355/mcshader-lsp/commit/551380a6ed00709287460b7d8c88e7803956052c) for detailed explanation.
