URL sanitization fails on URLs containing percent-encoding

[spencerwilson]

Describe the bug

URL sanitization is overly aggressive on URLs containing percent-encoded data

Steps to reproduce the issue

Run the following on v1.1:

>>> gazpacho.utils.sanitize('https://en.wikipedia.org/wiki/M%26M%27s')
'https://en.wikipedia.org/wiki/M%2526M%2527s'

Alternatively, on 7cc9488 with a tweak to get the package loadable, and logging str(url):

>>> gazpacho.get('https://en.wikipedia.org/wiki/M%26M%27s')
url http://https://en.wikipedia.org/wiki/M%2526M%2527s
...

(i.e., no change)

This results in certain URLs not being get-able. In my case en.wikipedia.org serves a 404 response.

To get 7cc9488 importable I changed

gazpacho/gazpacho/__init__.py

Line 2 in 7cc9488

from .soup import Soup

to

from .soup2 import Soup

Expected behavior

The valid URL I give is unchanged during sanitization, and is fetched successfully.

Environment:

• OS: macOS
• Version: 14.2.1

Python 3.11.3

Additional information

Seems like occurrences of % are getting rewritten as %25.
