Proposal: Allow to set facet on fields

[itsam]

Would be nice idea if for any of the selected fields in the module's configuration to have a flag (checkbox) next to it that when is selected to set this field as facet as well.

I believe it's straightforward and allows to create more advanced interfaces using typesense's javascript

For example

{"name": "dcterms_creator", "type": "string[]", "facet": true, "infix": true }   

I would say the most time consuming is on the UI rather than setting the "schema" to include "facet":true
At the moment I am doing this by PATCHing my collection but it's not optimal and have to re-patch in every re-index

Let me know what you think.
Thank you in advance
