bump to embedded-hal v1.0.0 (embedded-can)

[zpg6]

embedded-hal has released v1.0.0 which splits the CAN stuff into its own crate embedded-can. Same traits looks like.

embedded-hal v0.27.0 Frame: https://docs.rs/embedded-hal/0.2.7/embedded_hal/can/trait.Frame.html
embedded-can Frame: https://docs.rs/embedded-can/latest/embedded_can/trait.Frame.html

Are you open to bumping this if it is indeed a clean swap? I'd happily contribute the change and test on my esp-rs setup w/ 2 MCP2515s.

Would be greatly appreciated if you could test and PR!

One suggestion, I've seen other crates that have embedded-hal 0.x as an optional dependency. Maybe it's also worth doing that here?

The embedded-can stuff is indeed clean swap, but the bump to embedded-hal v1.0.0 has some breaking changes to SPI traits.

embedded-hal migrating 0.2 to 1.0 docs:
https://github.com/rust-embedded/embedded-hal/blob/master/docs/migrating-from-0.2-to-1.0.md#can-traits

This is a bigger job and maybe a separate preliminary PR.

Hi there!
My Rust knowledge is quite limited but, whenever the changes are in place for embedded-hal 1.0.0 I am happy to test it against my STM32411 and open a PR with an example.
