IID

* Add IID Logic (#63)

	- Only IID assumption on the data (i.e. the +ve and -ve samples for a particular embedding
	appear i.i.d from the true distribution
	- uses wilson_confidence_interval for binomial distribution to get better approximations for
	extreme similarity value (i.e. near 1)

* Fix: Theoretically exact IID (#63)

	Earlier IID bounded the error by (\epsilon + \delta).
	Modified it to now bound it by (\delta) as required.

* Fix linting errors (#63)

* Fix Lining Errors [2] (#63)
