[FEAT]: added Ranger as alternative to Range

[quenbyako]

Main differences between Range:

• compiled version checker can be reverted back to string, if necessary
• possibly, you can add support of inner comparison (in rounded brackets -> (), like in mathematical operations), as well as additional comparators, or range syntax (got a few ideas from this article)

My main goal was to revert back parsed range, so possibly we can optimize it a bit without loosing backward compatibility.
