ensure options on validations are passed into errors

[JoshDevs]

This PR ensures that the options that are sent in the validation are passed through to errors.

Custom options being set on a validation should be able to be accessed post validation as they would have been set to indicate a validation has failed for some reason.

Added a test case that checks for this.

@adzap Hi, this is a minor patch we've made to validates_timeliness. It makes the library more consistent with the standard Rails validators, as they all include **options when adding an error, e.g. PresenceValidator.

We'd like to get this merged upstream so we don't have to maintain our own fork, could you take a look?

Hi, I've asked to be added to maintainers so I can keep this library up to date and merge bug fixes like this. Let's maybe wait but at a certain point I'm interested in creating a fork maybe in a new GitHub team to allow multiple admins
