Fix for failing downloads

[janssen70]

I found, downloaded and tested your script few weeks ago: fine Started to integrate in my application this week: didn't work. Don't know why, did something change on wetransfer side?

main changes:

1. I had to change the url from https://www.wetranfer.com to https://wetransfer.com
2. because the Wetransfer app yield download links without recipient_id I made that path going as well

My copy includes changes not present in your master. I don't understand why. I recall I got my original from github as well. I am sorry this pull request is a bit untidy in that respect.

Feel free to pick an chose changes as you like.

@janssen70 @Sicos1977 I am trying to use the code in this pull request. I see the url is correctly generated and as the following form: https://wetransfer.com/api/ui/transfers/{0}/{2}/download?recipient_id={1} but I am getting <Response [404]> from the request call
