* Introduce a `Slot` type Instead of having some type definition that only was used in half of the code or directly using `u64`, this adds a new unit type wrapper `Slot`. This makes it especially easy for the outside api to know what type is expected/returned. * Change epoch duratioC * rename all instances of slot number to slot * Make the constructor private Co-authored-by: André Silva <andrerfosilva@gmail.com>
