Henry Gabryjelski 160d61682b Add lf em 4x70 autorecover
Also:
* common.h: Increase safety of some of the macros.
  Parenthesizing the macro parameters ... a best practice.
* firmware: partially-tracked source of "extra bits" messages.
  Add a TODO comment for further study.
* Improve reliability of `lf em 4x70 writekey`
  Authenticate w/new key after it is written.
  Particularly important for glass modules,
  or other tags with weaker coupling.
