Assertion functions adapted for rlang output

Most common checkmate functions, adapted to output rlang style error messages on failed assertions. The actual checking is done by checkmate::qtest(), checkmate::check_flag() and related functions.

R Type	Scalar	Vector
`logical`	`assert_flag(x)`	`assert_logical(x)`
`character`	`assert_string(x)`	`assert_character(x)`
`numeric`	`assert_number(x)`	`assert_numeric(x)`
`integer`	`assert_inumber(x)`⁴	`assert_integer(x)`
`double`	`assert_dnumber(x)`⁴	`assert_double(x)`
`integerish`¹	`assert_int(x)`	`assert_integerish(x)`
`naturalish`²	`assert_count(x)`	`assert_naturalish(x)`⁴
`factor`	³	`assert_factor(x)`
`complex`	³	`assert_complex(x)`
`raw`	³	`assert_raw(x)`
`Date`	`assert_day(x)`	`assert_date(x)`

¹ integerish refers to functional integers (numbers that are very close to integer values), regardless of type (integer or double )
² naturalish refers to functional integers restricted to the natural numbers (zero and positive numbers
³ No assertion functions are provided for scalar factor, complex, or raw
⁴ Not available in the checkmate package
