If we were to design the perfect type for representing a size

This type would have to be built on top of the existing
primitives and would therefore be less performant, which is a
shame and likely the reason it doesn't already exist.

ARM directly supports saturating arithmetic, so this approach
could be both practical and fast. However, x86 only supports it
in SIMD, so it's not ideal.
