I guess this is a related shortcoming. Turning a `factor` (that should be /
can be `ordered`) into `ordered` leads to what seems like an incorrect schema
print as the ordered flag is ignored -- flag should be 3 not 2.
```r
> pclass <- as.ordered(earth::etitanic$pclass)
> str(pclass)
Ord.factor w/ 3 levels "1st"<"2nd"<"3rd": 1 1 1 1 1 1 1 1 1 1 ...
> infer_nanoarrow_schema(pclass)
<nanoarrow_schema dictionary(int32)<string>>
$ format : chr "i"
$ name : chr ""
$ metadata : list()
$ flags : int 2
$ children : list()
$ dictionary:<nanoarrow_schema string>
..$ format : chr "u"
..$ name : chr ""
..$ metadata : list()
..$ flags : int 2
..$ children : list()
..$ dictionary: NULL

```
