/**
* The `Strong` class extends `Profunctor` with combinators for working with product types.
*
* `first` and `second` lift values in a `Profunctor` to act on the first and second components of a tuple,
* respectively.
*
* Another way to think about Strong is to piggyback on the intuition of
* inputs and outputs. Rewriting the type signature in this light then yields:
*
* ```purescript
* first :: forall input output a. p input output -> p (Tuple input a) (Tuple output a)
* second :: forall input output a. p input output -> p (Tuple a input) (Tuple a output)
* ```
*
* If we specialize the profunctor p to the function arrow, we get the following type
* signatures, which may look a bit more familiar:
*
* ```purescript
* first :: forall input output a. (input -> output) -> (Tuple input a) -> (Tuple output a)
* second :: forall input output a. (input -> output) -> (Tuple a input) -> (Tuple a output)
* ```
*
* So, when the `profunctor` is `Function` application, `first` essentially applies your function
* to the first element of a tuple, and `second` applies it to the second element (same as `map` would do).
*
* Adapted from https://github.com/purescript/purescript-profunctor/blob/master/src/Data/Profunctor/Strong.purs
