How to add Transactional trait

[tinkhauser]

I'm attempting to get the rust-radio-sx128x crate working with the nrf-hal. That hal hasn't yet implemented the v1.0.0-alpha.N embedded-hal traits.

So far compat() has solved all the trait errors except for blocking::spi::transactional. I'm unsure of how to add that trait to this crate.

Is it possible to add the transactional trait to this repo? Or do I need to fork nrf-hal and implement it there like you suggest here? rust-iot/rust-radio-sx127x#18 (comment)

Cheers!

Ahh, I didn't put it in because embedded_hal::blocking::spi::Transactional doesn't exist until v1.0.0-alpha.X...

In the past I had a polyfill for this, technically it opens a whole CS related can of worms but, might as well add have it here anyway (perhaps with a warning and link to rust-embedded/embedded-hal#180)?

@tinkhauser i threw a Transactional trait in there so you should be good to go with 0.1.3, let me know how it goes?
