Convert buffer to slice so user doesn't need unsafe

Wasn't sure if there is a reason it isn't like this already, but it's nice to save the step on the user end

Thanks! :)
I think it might have been chose to appease to a specific flash interface (rpi2040 is my guess) which requires a pointer. But I think generally a slice is nicer :)

I added a minor nit ;)

Ah, makes sense. .as_ptr() would work for those cases I suppose

All set!
