[I] SparkCastOptions should represent timezone as Option instead of String [datafusion-comet]

["andygrove (via GitHub)" <gi...@apache.org>]

andygrove opened a new issue, #1147:
URL: https://github.com/apache/datafusion-comet/issues/1147

   ### What is the problem the feature request solves?
   
   In Comet's native cast logic, we currently pass timezones around as strings and use empty strings to represent lack of timezones. This results in repeated parsing of timestamps that could be avoided.
   
   ### Describe the potential solution
   
   Change timezone from `String` to `Option<Tz>`
   
   ### Additional context
   
   _No response_
