Description of changes
Noted in #10243, passing
nullable
toibis.dtype
when using a string name forthe dtype leads to an unhelpful error. Instead, we should just support this.
This adds support for 'primitive' dtype specifications -- there's no defined
behavior for how to specify nested nullable types with a single keyword
argument, but this should cover most cases.
