* Returns a function of arity `n` from a (manually) curried function.

* @func
* @memberOf R
* @since v0.14.0
* @category Function
* @sig Number -> (a -> b) -> (a -> c)
* @param {Number} length The arity for the returned function.
* @param {Function} fn The function to uncurry.
* @return {Function} A new function.
* @see R.curry
* @example
*
* const addFour = a => b => c => d => a + b + c + d;
*
* const uncurriedAddFour = R.uncurryN(4, addFour);
* uncurriedAddFour(1, 2, 3, 4); //=> 10
