Given a range of numbers, find the largest and smallest palindromes which
are products of two numbers within that range.

Your solution should return the largest and smallest palindromes, along with the factors of each within the range.
If the largest or smallest palindrome has more than one pair of factors within the range, then return all the pairs.
Your solution should return the largest and smallest palindromes, if there are any.

## Example 1

The palindrome products are all single digit numbers (in this case):
`[1, 2, 3, 4, 5, 6, 7, 8, 9]`

The smallest palindrome product is `1`.
Its factors are `(1, 1)`.
The largest palindrome product is `9`.
Its factors are `(1, 9)` and `(3, 3)`.
The smallest palindrome product is `1` (`1 * 1`).
The largest palindrome product is `9` (`1 * 9` and `3 * 3`).

## Example 2

Given the range `[10, 99]` (both inclusive)...

The smallest palindrome product is `121`.
Its factors are `(11, 11)`.
The largest palindrome product is `9009`.
Its factors are `(91, 99)`.
The smallest palindrome product is `121` (`11 * 11`).
The largest palindrome product is `9009` (`91 * 99`).
