fix(aya-log): print &[u8] using full width

[GrigorenkoPV]

Otherwise you cannot distinguish &[1u8, 0u8] from &[0x10u8] (they both become 10)

Looks like this change would belong to *HexDebugFormatter and not inline here?

[vadorovsky]

I agree. Let's make these changes here:

aya/aya-log/src/lib.rs

Lines 208 to 219 in ab000ad

	impl<T> Formatter<&[T]> for LowerHexDebugFormatter
	where
	T: LowerHex,
	{
	fn format(v: &[T]) -> String {
	let mut s = String::new();
	for v in v {
	let () = core::fmt::write(&mut s, format_args!("{v:x}")).unwrap();
	}
	s
	}
	}

aya/aya-log/src/lib.rs

Lines 232 to 243 in ab000ad

	impl<T> Formatter<&[T]> for UpperHexDebugFormatter
	where
	T: UpperHex,
	{
	fn format(v: &[T]) -> String {
	let mut s = String::new();
	for v in v {
	let () = core::fmt::write(&mut s, format_args!("{v:X}")).unwrap();
	}
	s
	}
	}

I don't think Rust has a formatting option of "print as many zeroes as needed", so it's not really possible to do this in generic context. And since specialization like in C++ does not exist in (stable) Rust (yet?), I had to hardcode the width of 2 somewhere else.

[alessandrod]

I'm not sure what you mean but UpperHexDebugFormatter (perhaps misnamed) is only used for for impl Format for &[u8] so with your change now it becomes dead code. So we might as well do the change there?

[GrigorenkoPV]

I've done what #1008 (comment) suggested and added a test as well
