CB2S: Couldn't recognize input data

[lanrat]

I used ltchiptool to create a firmware dump of a DY-RQ400A containing a CB2S/BK7231N. However upk2esphome is unable to parse the generated flash dump just giving the error: Couldn't recognize input data. Multiple dumps were taken, all with the same md5 and all give the same error.

Copy of the flash:

This is a TuyaOS 3 device which has changed its storage structure, and isn't currently compatible with existing tools.

There may be an adjustment in the future, but not enough information has been collected yet. Either way, this device doesn't have pin configuration in storage as it is a TuyaMCU device.
