Refactor ChangeFeedCommand.actor.cpp for Readability and Modularization

[sanowl]

Modularized Code*: Separated command handling into individual functions (handleStreamCommand, handlePopCommand).
2. Consistent Error Handling: Improved error handling across functions with detailed error messages.
3. Enhanced Readability: Added comments and improved code structure for better readability.
4. Namespace Usage: Encapsulated helper functions within an unnamed namespace for better encapsulation.

This looks great! thanks for the refactor.

It might be great if a const std::unordered_map<std::string_view, decltype(some_general_handle_function_type)> could help defeat this if/elseif/else monster.

Not sure if we want this SLN file since on our side we do not support MS windows -- it is supported by some other people I do not know. @ammolitor might know how to contact them.

[xis19]

Not sure what happened, but I just commented and they are not showing up. So forgive me if this commit is commented twice.

Can we move this outside the ACTOR? So this is not being constructed repeatly when the function is called..

[xis19]

This cast is not necessary since Future(const T&) is not defined as explicit.

[xis19]

Not quite sure if a std::function would be better than a raw function pointer, but anyway.

FYI: I have sent you a pull request to your repo for the source formatting issue.

[xis19]

Um... This definitively would not pass the CI test because we are using rather than 4 spaces. I have no idea why but that's the rule.
