Add support for AnimeWatch

[RaulRohjans]

Is your feature request related to a problem? Please describe.
Not related to any problem. I wanted to suggest adding AnimeWatch to the project.

Describe the solution you'd like
The website is a bit messy in terms of organization but downloads are very fast (max of 8 MBps), video files are very small size and encoding quality is significantly better than gogoanime. There is no cloudflare protection and no redirects to download, the website works with direct links.

Describe alternatives you've considered
None

Additional context
None
