chore: specify ranges for all integers

Ranges are not needed inside of tesbenches.
Resolves #22.

Configuration is same for one compilation, it cannot change.
Thus it does not make sense to be a port.
Resolves #13.

chore: add documentation to the code

feat(link): add error handler entity for managing data link errors (lane misalignment, frame misalignment, not in table error, disparity error, unexpected character error)
