Add ability to set default masking state

[TPNils]

When using "Mask Combat Number Display", it resets when I reload the page and shows the full numbers again.

Hey Spy, as a temporary way to make the numbers always masked, open the combat-numbers.js file, do a search for the function getIsMask and replace

getIsMask() {
    return this.isMask;
  }

with

getIsMask() {
    return true;
  }

Do note that you cannot toggle the numbers back on doing it this way. It will always be masked!

A default mask state can now be set with the "Mask Default State" setting in module settings. Cheers.
