   ### Is your feature request related to a problem or challenge?
   
   I've been looking into how best datafusion's `date_bin` function should be 
made timezone aware. One aspect of this work is handling local timestamps that 
have no representation in a particular timezone. To be able to handle these we 
will need to know where gaps start and end.
   
   ### Describe the solution you'd like
   
   I would like to see. the addition of a `GapInfo` structure, modelled on 
`chrono-tz`'s 
[`GapInfo`](https://docs.rs/chrono-tz/latest/chrono_tz/struct.GapInfo.html), 
that presents the start and end of a gap using arrow native 
`ArrowTimestampType`s.
   
   ### Describe alternatives you've considered
   
   The alternative is to parse the timezone string as a `chrono_tz::Tz` and use 
`chrono`'s `GapInfo` data.
   
   ### Additional context
