Byte decode error

close #88

[Kerollmops]

Thank you, I tried but haven't finished yet. So, you take the lead and I will accept your PR!

I am wondering if introducing a custom public Result type named CodecResult, could be better.

pub type CodecResult<T> = Result<T, Box<dyn Error>>;

When I switch from zerocopy to bytemuck I will change this error string into a nicer error, more precise!

[Kerollmops]

Suggested change

	fn bytes_decode(_bytes: &[u8]) -> Result<Self::DItem, Box<dyn std::error::Error>> {
	fn bytes_decode(_bytes: &[u8]) -> Result<Self::DItem, Box<dyn Error>> {

By importing the Error trait into the scope.

[Kerollmops]

Suggested change

	let key_bytes: Cow<[u8]> = KC::bytes_encode(&key).map_err(|e| Error::Encoding(e))?;
	let key_bytes: Cow<[u8]> = KC::bytes_encode(&key).map_err(Error::Encoding)?;

[Kerollmops]

Suggested change

	Encoding(Box<dyn std::error::Error>),
	Decoding(Box<dyn std::error::Error>),
	Encoding(Box<dyn Error>),
	Decoding(Box<dyn Error>),

Why not exposing an anyhow Result instead?

Why not exposing an anyhow Result instead?

I don't want to bring one more dependency in this crate, don't want to force users to use anyhow, using anyhow here would not bring interesting features here, and anyhow has been design to be used by binary crates.

Exposing a type alias will work just fine :)
