Is your feature request related to a problem or challenge? Please describe what you are trying to do.

It is fairly common to want to perform an operation on the values of a DictionaryArray directly, currently this requires decomposing into ArrayData, updating the child data, and then reconstructing the dictionary.

Describe the solution you'd like

I would like a safe API for this operation

Describe alternatives you've considered
