but this avoids having to load the achievement icon during gameplay which causes micro-stutter
* avoid loading and resizing the achievement icon each time it's unlocked
* Local_Storage: avoid allocating buffers unless `stbi_load()` was successfull
* remove the code which adds custom Windows fonts but keep scaling
* only attempt to load achievements images when hook is ready
* cleanup overlay images on unhook
* free the detector when we get a renderer hook instance
* lock everywhere!
* prefix the debug messages for a cleaner debug log
