feat: accept any type of range in range assertions

[haraldmaida]

Currently assertions that take a range as expected value support only RangeInclusive. This shall be enhanced to support more types of ranges.

The assertions is_in_range, is_not_in_range, has_length_in_range and has_char_count_in_range have been changed to support any type of range from the Rust core lib. More precisely, any type that implements core::ops::RangeBounds is now supported.
