Support for geo data

[Robinlovelace]

This looks great! One feature request I have in mind is support (either via new functions/functionality or via documentation if it works out of the boxx) for spatial data. See this by @cboettig for inspiration: https://github.com/cboettig/duckdbfs#spatial-data

Another potential source of inspiration is sf's support for tidy operations, it great how summarise() and other functions 'just work' with tidy verbs: https://r-spatial.github.io/sf/reference/tidyverse.html
