Add KFM5KAIFA support

[IoannisPZP]

• Add whitespace as possible character (used in messages)
• Added KFM5KAIFA sample
• Fixed typo for OBIS detection failure
• removed assert for profilegeneric (not sure about this)

Hi @IoannisPZP, thanks for your contribution! I've got a few remarks:

• Could you use convententional commit subjects, so the releaser CI will version the next release properly?
• Could you please split your four contributions into (I think three: whitespace and KFM5KAIFA are a single "feature") seperate comments? I'd like to avoid bundling seperate changes/improvements into combined commits

I am a bit unsure about including " " as a CHARACTER, as whitespace is treated differently when tokenizing. But then again, if the (improved) parser is able to parse all test messages correctly, it's fine by me.

Hi @IoannisPZP, did you get a chance to look at my feedback?
