I'm trying to use Arrow to send data between a Julia (Arrows.jl) and a Rust
(Polars) app.
However, when I write a table containing Date, it is read by Polars as
Extension("JuliaLang.Date", Date32, Some("")), and Polars complains with
```
Cannot create polars series from Extension("JuliaLang.Date", Date32,
Some("")) type
```
I would have expected one of the following things would happen:
1. When writing the Arrow file, the type is converted to a suitable Arrow
type (e.g. Date32 ),disguising its origin.
2. When reading the Arrow file, Polars would ignore the origin
(JuliaLang.Date, which seems to just be a name) and recognize it as Date32 or
whatever.
Instead, what seems to happen is that it is encoded as an extension type and
Polars does not know what to do with it. Is this expected behavior?
