v0.13.5

• Changes
  • Add Nerves.Runtime.FwupOps to make it easier to run commands from the
    revert.fw (older) and ops.fw (newer) files. The firmware revert logic
    had always used this, and this makes getting to factory reset and preventing
    reverts easier. Some operations aren't available on all Nerves systems.
  • Various documentation and syntactical updates instigated by Elixir 1.15.
