Ability to define mask placeholders

[probil]

It would be nice to have ability to add/remove/replace custom mask placeholders.
Predefined placeholders are not enough in some cases.
Currently the idea is to pass placeholder definitions to the plugin options. This will apply to all masks.

Vue.use(VueMask, { 
  placeholders: {
    // define new placeholder
    'S':  /[a-z]/.test,

    // remove existing placeholder
    '#': null,

    // replace existing placeholder
    'N':  /[a-z]/.test,
    },
  },
});

Plus we should be able to do the same for one mask only.

<template>
  <input v-mask="['(', /[1-9]/, /\d/, /\d/, ')', ' ', /\d/, /\d/, /\d/, '-', /\d/, /\d/, /\d/, /\d/]" />
</template>

Hello!
You need something like this to have maximum flexibility.
No way to raise to uppercase
