feat!: use Go 1.18 Generics

[maxbrunet]

This adds type parameters and remove the use of interface{} and type assertions for improved type safety. I have not observe any significant impact on performance (positive or negative).

It is obviously a breaking change.

Are there any plans to merge this or make a generic version of this library?
