sugar feature: string length

[Eomm]

🚀 Feature Proposal

Add a .length(24) method as a shortcut for min + max length.

Motivation

Right now to add a check for a string I need to write:

S.string().minLength(24).maxLength(24)

Example

S.string().length(24)

WDYT?

I like the idea of having shortcuts. However, diverging from the JSON Schema API could bring issues in the future.
What if length would be added in the spec with a different meaning?
As well the saving or the productivity boost isn't that much.

Maybe you could have a shortcut definition for your usecase

const sLenght = (length) => S.string().minLength(length).maxLength(length)
S.object().prop('foo', sLenght(24))
