Uint8ClampedQueue class Null safety

A QueueList that efficiently stores 8-bit unsigned integers.

For long queues, this implementation can be considerably more space- and time-efficient than a default QueueList implementation.

Integers stored in this are clamped to an unsigned eight bit value. That is, all values below zero are stored as zero and all values above 255 are stored as 255.
