Purpose of Box in StreamCDC struct

[tazjin]

Hey!

The StreamCDC struct currently contains a Box<dyn Read>, which requires an additional heap allocation and potentially prevents some compiler optimisations by obscuring the reader type.

Is there a particular reason for this Box that isn't immediately obvious, or would you accept a change to parameterise StreamCDC over an R: Read, such that monomorphisation can occur?

Thanks for this crate! :)

It was that way because I didn't know any better. In an effort to learn Rust more thoroughly I went ahead and made the change. Thank you for pointing it out, and offering to fix it.

Great, thank you! :)
