Smartshunt Unsynchronized SoC

[fti7]

When the SoC is not synchronized, it throws an Exception:

Exception in thread Thread-2:

With commit https://github.com/birdie1/victron/commit/33fff2f8067e71819d944f8e81c5cdf5f1bbd671 it will catch the ValueError and gives back the incoming string. Currently I don't have a device to test it.
