Deriving TryFromBytes warns about non_camel_case_types

[bluurryy]

When you derive TryFromBytes on an enum like this:

#[repr(u32)]
#[allow(non_camel_case_types)]
#[derive(TryFromBytes)]
pub enum Code {
    I32_ADD,
    I32_SUB,
    I32_MUL,
}

You get warnings about non_camel_case_types from the expanded code:

// ...
#[repr(u32)]
#[allow(dead_code)]
enum ___ZerocopyTag {
    I32_ADD,
    I32_SUB,
    I32_MUL,
}
// ...

Adding #[allow(non_camel_case_types)] to the ___ZerocopyTag will fix this.

Thanks for reporting this! I've opened a fix in #2057.
