Currently createEntityAdapter provides no type checking for the id of an entity

This prevents type checking when using the selectors, and means that the return type of functions such as getAllIds returns EntityId[] rather than a type specific to the entity.

Introducing an (optional) type parameter for Id will solve all of these propblems, and also allow for the newtype pattern to ensure types between different adapters do not get mixed up

type MyIdType = string & { readonly __tag: unique symbol }
