Export rules independently

[jaggy]

It might be better for userland if they need to import the rules they need, rather than adding 20 different rules when the Validator is pulled in.

I'm still not sure how to do it but that's the end goal.

Also think of a good developer experience for loading all, of the core extensions.

Here's the proposed method

import { required, between, min, file } ax extensions from '@artisanstudio/validate.js/extensions'

Validator.load(extensions)

For loading ALL of the extensions, I would love it to have an API of Validator.loadCoreExtensions() although I'm not sure how that would work since if we do require on the javascript side, it'll already pull in all the dependencies.

The only thing I can think off is:

import * as CoreExtensions from '@artisanstudio/validate.js/extensions'

Validator.load(CoreExtensions)

Though, I'm not sure how the DX is.
