[I] [C++][Acero] hash_one not implemented for dictionary and other types [arrow]
nealrichardson opened a new issue, #44661:
URL: https://github.com/apache/arrow/issues/44661
### Describe the enhancement requested
Observed while adding R support in https://github.com/apache/arrow/pull/44652. If you call this function on a Table/Dataset that has dictionary type columns (`factor` in R), you get
```
NotImplemented: Function 'hash_one' has no kernel matching input types
(dictionary<values=string, indices=int8, ordered=0>, uint8)
```
It appears to have been left off in https://github.com/apache/arrow/pull/12368 and no followup issue was made. I don't see any technical reason for not doing it, but I'm not familiar enough with the C++ compute code to see how to add it.
### Component(s)
