IBT-2XS rogue high temp fix

Fix for

While I initially thought it was a good idea to shorten the manufacturerdata comparison from "index", 0, "00000000" to "index", 2, "000000" in

#110

to include both 2X and 2XS versions in one decoder, it wasn't then clear that the IBT-2XS also sends 02 prefixed manufacturerdata of weirdly unrealistic high temperatures every now and then :)

We might want to wait just a bit before merging just to see if the other user also has the same 02 occurrences.

I think we can actually merge this, as it's very unlikely that the other user's issues isn't the same 02 prefixed manufacturerdata, and even it it was still happening with the now defined

… "manufacturerdata", "=", 28, "index", 0, "00000000", "|","manufacturerdata", "=", 28, "index", 0, "01000000"

there wouldn't be much we could do about it on the decoder side.

What do you say?
