feat: Derive more traits

[Antosser]

This PR adds more derives to the Size struct. The following code was also removed because it could simply be derived.

impl PartialEq<Size> for Size {
    fn eq(&self, other: &Size) -> bool {
        self.bytes() == other.bytes()
    }
}
impl PartialEq<&Size> for Size {
    fn eq(&self, other: &&Size) -> bool {
        self.bytes() == other.bytes()
    }
}
impl PartialOrd<Size> for Size {
    fn partial_cmp(&self, other: &Size) -> Option<core::cmp::Ordering> {
        self.bytes().partial_cmp(&other.bytes())
    }
}
impl PartialOrd<&Size> for Size {
    fn partial_cmp(&self, other: &&Size) -> Option<core::cmp::Ordering> {
        self.bytes().partial_cmp(&other.bytes())
    }
}
