Update embedded hal traits

[T-Bakker]

This PR updates the embedded-hal dependency and switches to its replacement embedded-can. This means that now socketcan and bxcan share a common trait in the embedded-can library, which me really would like.

Wondering what's blocking this?

Would be nice to have this

@adamgreig could you please take a look at this?

[dimpolo]

Thanks for the quick response @adamgreig but that's not quite what I meant 😅

@jonas-schievink seems to no longer be maintaining this crate and I was hoping you could either get this merged and released or facilitate someone else doing so.

[adamgreig]

Yep, can do. I had hoped to have a clean merge button after reviewing but I'm not technically on the team for it 😅

Is anyone interested in helping to maintain this crate? I can get this merged and do a release (though probably not for a day or two, I'm travelling atm) but more usefully if anyone is interested I can get you set up.

[dimpolo]

Awesome, thank you!

I wouldn't mind helping out :)

This is now released at 0.8. Thanks for offering to help! I don't have time to set it up right now but will try and get it sorted in the next few days. Ping me if you get bored of waiting!
