Also update the XMOS firmware automatically when firmware was build using the ESPHome dashboard. #243
Description
Summary
The factory ESP firmware has a XMOS firmware embedded, if the version of that firmware does not match the installed firmware on the XMOS, the XMOS gets flashed with the embedded on.
If the firmware is built manually using the dashboard (satellite1.yaml) the XMOS firmware specified in the substation section gets embedded, but it won't get installed automatically if it differs from the installed one.
To have a consistent user experience we want to include the auto-updater also to the satellite1.yaml config.
