Adds support for checking the timestamp inherent while validating a block (#494)

Browse Source 
* Adds support for checking the timestamp inherent while validating a block

This adds support for checking the timestamp inherent while validating a
block. This will use the relay chain slot number * relay chain slot
duration to calculate a timestamp. This timestamp is used to check the
timestamp in the timestamp inherent.
