Pull request description:

  Previously we've used `try_into().expect()` because const generics wer
  unavailable. Then they become available but we didn't realize we could
  already convert a bunch of code to not use panicking conversions. But we
  can (and could for a while).

  This adds an extension trait for arrays to provide basic non-panicking
  operations retutning arrays, so they can be composed with other
  functions accepting arrays without any conversions. It also refactors a
  bunch of code to use the non-panicking constructs but it's certainly not
  all of it. That could be done later. This just aims at removing the
  ugliest offenders and demonstrate the usefulness of this approach.
