Implements SSL-EY

[jameschapman19]

Adding SSL-EY from (https://arxiv.org/abs/2310.01012, https://neurips.cc/virtual/2023/80864)

For the moment I've implemented the simple version but it should in principle plug into multicrop like SWAV.

Will have a stab at running the shorter benchmarks shortly.

hey @jameschapman19 thanks for contributing. I'll try to start checking your code soon.

@vturrisi - just working through ironing things out perhaps a premature PR I just wanted to get a hang of the CI. Will give you a shout when I'm passing more of these.

@jameschapman19 no worries, take your time :) and ping me when you are done
