Merge #79

79: Update panic-semihosting to v0.3.0 r=japaric a=maxekman

To support the latest nightly. Similar to rust-embedded/cortex-m-quickstart#33.

Would also be great to have a new release of this package and update the discovery project/book to compile with latest nightly.

Note that I'm very new to the Rust space and these projects and not really sure if bumping this dependency have any other implications!
