* This method is like `lastIndexOf` except that it performs a binary

* @since 4.0.0
* @category Array
* @param {Array} array The array to inspect.
* @param {*} value The value to search for.
* @returns {number} Returns the index of the matched value, else `-1`.
* @example
*
* sortedLastIndexOf([4, 5, 5, 5, 6], 5)
