filtering chapter list by TL language doesn't work

[typhoon71]

Describe the bug
filtering chapter list by TL language doesn't work, you get a 400 response

To Reproduce
import mangadex

import mangadex

api = mangadex.Api()
chapter_list = api.chapter_list(manga="30196491-8fc2-4961-8886-a58f898b1b3e", chapter=35, limit=20, translatedLanguage='en')

Expected behavior
get only the chapter translated in ''en"

The call works fine till I add translatedLanguage='en'; "translatedLanguage" should be a valid parameter.
Passig translatedLanguage=['en'] doesn't solve it (the is Array of strings, so I tried but no dice).

bw: awesome work, I wanted to do some mangadex-API to python3 myself, but this is just right for me.

I looked into it and discovered I was not parsing some parameters correctly, I just made some changes and saw that many other functions have this issue too. It was my bad for overlooking this issue but it should be fixed by now. I still need to create the release, but you can clone the repo and install it with setup.py if you want. Also if you encounter any other issues, please let me know.

Thanks a lot, I will test this as soon I get a bit of time, this weekend I suppose.

Played around a bit before going to bed and spotted something: I think "sacanlation_group_id" should be "scanlation_group_id", as it's in mangadex API.

More serious testing later as I said, but seems good to me.
