Getting the Json Out from the MQTT image in Home Assistant

[sca075]

First of all, I know there is a card that already do it and it is installed in my instance.. it works fine. It is just a question to understand the how to.. I did program in Python (the same script that use the card). but I do not get a clear readable data out from the embedded json in the image. I get something like.. Keyword "ValedudoMap", Data: b'x\x9c\x8d[]\xab]9r\xfd/\xe7\xf94l}K~\x0bI\x1e\x06f\xa0!\x90\x97`\x9a\x13\xfbv\xcf\x05\xb7...

that is a bites array not text format.. probably compressed.. but completely undocumented as per most of what we can found on the guides... I can get the map data from the robot json via CURL but.. it would be nice to know how to decode the data embedded in the PNG.
