mini issue: Possibility of testing if a number is strictly greater than another

[arthurzaneti]

When using, for instance checkmate::check_number(1, lower = 1) this will evaluate to TRUE, could there be an argument to numeric and number testing functions for testing if a number is strictly greater than 1. Something like checkmate::check_number(1, bigger = 1) that would evaluate to false.

Thanks in advance
