OBIS ID 96.1.0 not decoded

[Froschie]

Hello,

I was playing around with your ESP based SML reader in comparison to a RasPi based solution.

Power values are reported correctly, but OBIS code 96.50.1 with the serial number is not properly decoded, only RAW HEX message is shown.

Via MQTT I get: /sensor/1/obis/1-0:96.50.1/1/value ISK /sensor/1/obis/1-0:96.1.0/255/value 0a 01 49 53 4b 00 05 39 7f b1

But serial number should be shown as: 87654321 Would be great if the decoding could be improved.
