Code breaks when messages are incomplete

[davidmarcelbaum]

Incoming messages are sometimes incomplete. JSON decoding can therefore not be done and the GUI breaks at that point during "Helment_signal_sampling.fetch__sample"

This has been solved by adding to exceptions in "try - except" fashion: JSONDecodeError (1) and ValueError (2)
1: fixes decoding not being performed because of keys not being correct
2: fixes array generation not being able to be performed because number of elements (values) for each key are different
