x-mask: Cleanup of event listeners

[beholdr]

Hi,
Found a bug when using x-mask with Livewire. Problem is sometimes input changed by Livewire and mask directive intiated every time. Adding cleanup of event listeners fix this issue.

Unfortunately don't know how to make correct tests for this situation without LW part, but you can check it on this wirebox: https://wirebox.app/b/4kwle

To reproduce:

1. Fill both inputs with 12345 string
2. Click toggle button
3. Try to enter 6 (to get 123456 string) in both fields. First field has weird behaviour, second field is OK.

Second field has patched version of mask plugin.

Definitely should be there!

I am a bit surprised to learn event listeners accept abort signals. That's pretty cool.
