Provide support for auto firmware updates on some popular third party dongles. Using firmware builds from: https://github.com/darkxst/silabs-firmware-builder
OTBR supports a wide range of firmware versions, thus any update of OTBR itself is unlikely to require new firmware builds. So these third-party firmware should never block a new OTBR release.
NB: SLZB-07 support requires the device has the cp2102 eeprom flashed with manufacturer strings, only newer stock has this from the factory. However SMLIGHT will be releasing a tool for user to update eeprom content on older devices.
