v1.0.0

Added

• Sensor auto-population: when the integration is set up for the first time, it will no longer
  populate every possible sensor. Rather, it will wait for the first data update from the add-on (or
  alternative method) to populate sensors at that time. If sensors are added to the WS in the
  future, they will be added automatically
• Timestamp sensor (Last Rain, Last Lightning) persistence across reboots of HA
• Config Flow validation to prevent bad MACs from being entered
• Multiple weather station configuration: if another weather station needs to be added, just need to
  add the integration again for the new MAC; the service is now aware of other config entries
• Error text in config flow

Changed

• All sensors are now enabled by default. This does not effect current installations, but is good
  for new installation to show all available sensors and allow the use to choose what to hide
• Known sensors persist over a restart of HA or reload of the integration
• Calculated fields now show unknown instead of unavailable when their dependent sensors are not
  available
• Firmware version shown on the device page: right now this only seems to show up on new instances
  of the integration
• Rename of "Lightning Strike Timestamp" to "Last Lightning Strike"

Housekeeping

• Lots of code refactoring
