webp-imageio needs Java 9

[ThexXTURBOXx]

I only noticed today that the new version of webp-imageio I included needs Java 9 in order to work.
So, I should either fork it and downgrade to retain compatibility with Java 8 or migrate to a different one or remove it.
I would think it is much too overkill to fork it (as I did with dex2jar), just for the sake of providing a way to read webp images.
And since I don't see any other properly updated fork, I would suggest removing it.

Update: After some internal communication, I spun up a fork: https://github.com/ThexXTURBOXx/webp-imageio
It is compatible with Java 8 (at least it compiles, did not test thoroughly yet),
So, maybe let's go with that one?
