Incorrect amount of selected values in checkbox filter when values don't match options

[LeopoldArkham]

Here the amount of selected values reported by the component doesn't match the amount of checked checkboxes because the `values` prop contains a value that has no match in the `options`

E.g.:

<CheckboxFilter
  values={[0, 1, 3]} // No value '3' in the options but the component will report three values selected
  options={[
    {label: '...', value: 0},
    {label: '...', value: 1},
    {label: '...', value: 2},
  ]}
/>

Additionally the component might issue a warning when values don't match the options.
