[bug] Configuration changes do not save

[Moovry]

Version
Minecraft 1.14.3 / Mouse Wheelie v1.24+1.14.3
Describe the bug
Mouse Wheelie configuration changes made through Mod Menu do not stick. Settings do not save.

To Reproduce

1. Change configuration settings for Mouse Wheelie using Mod Menu
2. Save changes in Mod Menu and return to the game
3. Observe that configuration changes did not stick because mod behaves the same way as it did prior to attempting to change configuration
4. Confirm that no configuration changes were saved by checking Mod Menu -> Mouse Wheelie
5. Observe that %appdata%.minecraft\config\mousewheelie.hjson is an empty, blank file

Expected behavior
Saved configuration changes for Mouse Wheelie in Mod Menu should actually be saved.

That's a Tweed bug I'm soon™️ going to fix.

A temporary fix is to delete the empty config file and let the mod recreate it.
