Pass requests session to mwclient

This means it uses our configured user-agent, as well as any cookies.

This was needed to save https://wiiki.wii-homebrew.com/Hauptseite and https://breath-of-the-wild.wii-homebrew.com/Hauptseite which are behind cloudflare. I completed the cloudflare challenge in my browser, and then saved the following into a file named cookies.txt (where 1698010873 is the expirey time as a unix timestamp - probably it could have been anything, and longalphanumericstring was the value seen in firefox's devtools, and the values are separated by tabs, and there was no trailing newline):

# Netscape HTTP Cookie File
.wii-homebrew.com   TRUE    /   TRUE    1698010873  cf_clearance    longalphanumericstring

Then running with --cookies cookies.txt worked properly. Note that I also changed the user-agent to match what firefox currently uses (and what was used when I completed the challenge); I'm not sure if this was actually needed:

Makes sense. Thanks! It's unfortunate that so many wikis are behind cloudflare, but it can't be ignored. I wonder if we can identify such cases and print an informative error with instructions.
