BREAKING CHANGE: Require [@hapi/joi][] ^16.0.0.

BREAKING CHANGE: module now exports an object.

If you have existing code like

const semver = require('joi-extension-semver')
const Joi = require('@hapi/joi').extend(semver)

update it to

const { semver } = require('joi-extension-semver')
const Joi = require('@hapi/joi').extend(semver)

BREAKING CHANGE: semverRange is now a seperate type from semver.

If you have existing code that calls .validRange() like

const semver = require('joi-extension-semver')
const Joi = require('@hapi/joi').extend(semver)
Joi.attempt('>=1.2.3', Joi.semver().validRange())

update it to

const { semverRange } = require('joi-extension-semver')
const Joi = require('@hapi/joi').extend(semverRange)
Joi.attempt('>=1.2.3', Joi.semverRange().valid())
