v0.9.0

• New features
  • Add initial support for using the VintageNet.PowerManagerto manage the
    power to cellular modems. This allows VintageNet to power on and off a
    modem as needed and if it becomes unresponsive. To use this, you will need
    to provide an implementation of VintageNet.PowerManager that can control
    the GPIO (or whatever) connections that enable power and can send
    appropriate UART commands to power off. This only has been tested with
    Quectel BG96 and EC25 modems, but should be applicable to all modems.
  • Synchronize with vintage_net v0.9.0's networking program path API update
