feat: allow stacking of client.request() decorators + code improvements

[FAReTek1]

I did this while trying to debug #451 (still not resolved)

• Allows for stacking of @client.request by actually returning the function from the decorator
• General code style improvements in the cloud requests system. Doesn't actually change functionality
  • use !r flag in f string instead of surrounding replacement text in ''
  • extract function.__name__ if name is None else name
  • rename function to _function to avoid shadowing variable in outer scope
  • Using zip() for iterating through a string, 2 chars at a time, instead of using range len and some multiplication/divison

I have improved some indentation

I will merge this before more conflicts occur, but it should be tested just to be sure
