Support for additional deck.gl layers like terrain layer or h3 clusters?

[cboettig]

Is it already possible to interleave other deck.gl layers with lonboard's maps? E.g. can we add a deckgl terrain layer or a deck's h3 clusters or do these need to be implemented first as Lonboard layers?

They need to be implemented first as Lonboard layers to provide validation for input parameters and connect to the javascript layer description. PRs are welcome, and I can point you to how to implement additional layers. E.g. #302 (comment)
