AccessWidener Loader
Remaps and loads any number of accesswideners from the .minecraft/config/accesswideners
folder (it will generate it after first launch). Useful for example if you want to use a jar mod with fabric but it crashes due to trying to access inaccessible fields / methods / classes. Version independent.
For advanced users: It can only remap accessWideners from the mapping set currently used by the game, but luckily loader 0.15+ changed to use mapping io which means you can launch the game with tiny v2 mappings, which support multiple namespaces. So if you use merged yarn mappings at runtime, you can use named accessWideners instead of just official and intermediary ones. There is an example on using this for Prism / MultiMC in the github readme.
