Exclude values (such as "") from Facet component

[tanza-s]

Is your feature request related to a problem? Please describe.
I am building a facet component for a field that is blank for some records or otherwise has a field I don't want visible. I would like an option within the component that allows me to exclude certain values from the facet component.

Describe the solution you'd like
It'd be great to have this be an array that I can set within the React component itself. This is the pattern that we used in Searchkit.

<Facet
    field="get_major_filter"
    label="Major"
    filterType="any"
    isFilterable={true}
    **exclude={["", "Non-degree"]}**
/>

Describe alternatives you've considered
I can't think of a way to do this outside of building a custom facet component, which I really don't want to do. For now, allowing "" and "Non-degree" to display is good enough, but it looks pretty bad (the blank string is just a checkbox).
