[REQUEST] format `requests.structures.CaseInsensitiveDict`

[nschloe]

Rich pretty-prints dictionaries, but not yet requests's requests.structures.CaseInsensitiveDict. Given the ubiquity of the package, perhaps it's worthwhile including it.

MWE:

import requests
from rich import print

res = requests.get("https://google.com/")

print(type(res.headers))
print()
print(res.headers)

<class 'requests.structures.CaseInsensitiveDict'>

It would probably be easier to add a __rich_repr__ method to the object in requests.

This might give nicer output:

print(dict(res.headers))
