Refinement overload added to 'every' functions

[mlegenhausen]

I have added Refinement overloads to the every function of ReadonlyArray, ReadonlyRecord, ReadonlySet and their mutable counterparts.

Example

import { every } from 'fp-ts/ReadonlyArray'
import { isNumber } from 'fp-ts/number'

declare const as: ReadonlyArray<string | number>
every(isNumber)(as) // ReadonlyArray<number>

Thanks @mlegenhausen, released.
