create data frame from records about explorer

[josevalim]

I think from_records can be a bit misleading because of Erlang records. My suggestion would be to go with from_list. It has the benefit we can even change it to support lists of maps, lists of tuples, etc in the future.

Oh totally, from_records or from_list_of_maps (the former certainly has a better ring to it) has been on the list and I'm feeling that pain as well in my use of it. Your solution looks good! I'll have a think as to whether I can serialise it and do the conversion rust-side to avoid a couple potentially expensive passes over the array elixir-side. This is one of the challenges with Polars being based on Arrow, which is columnar, vs Elixir records being row-oriented.

Good point! I like from_list. I'm less enamoured with the inverse in to_list but I think I can get over it. 😛

@kimjoaoun sure! Feel free to have a run at it :).

Hi, @cigrainger can I get this one?
