[PR] add avy-goto-end-of-line function

I think this function could be useful for some people, and thus is worth adding, It mirrors avy-goto-line behaviour and then jumps to the end of the line

Disclaimer: I'm very new to the open source world (especially the elisp part of it), so I don't know if my code meets the standards of your project and any pointers would be very much appreciated

Thanks, merged with some minor corrections. One minor suggestion is to improve your Git username and maybe email, but it's up to you.
