fix(filter): remove unsupported Vue.filter

Description

Vue 3 upgrade gives errors due to the deprecated Vue.filter. This PR fixes this issue by removing the filter altogether. As mentioned by Ronald further down we can use the already exported masker directly instead.

For example:

<template>
  <div> {{ masker('1234', '###-#').masked }} </div>
</template>

<script>
import { masker } from 'vue-input-facade'

export default {
  setup() {
    return { masker }
  }
}

</script>

Note: Not marking this as a breaking change as the existing beta branch was already broken for Vue 3.
