Firmata strings encoded incorrectly

[zfields]

This needs a patch rev [v2.5.6]. I encoded Firmata strings directly (not as two bytes), including the Firmware name, but I couldn't detect it because it is ASCII (7-bits), and I had parsed the firmware name incorrectly.

I was refactoring the parser's firmware string decoder to use your logic for strings, when I realized what I had done.

I have the pull request ready to patch...

I discovered it on the ESP8266, because your node client parses the firmware name. I didn't see it before, because the analog data scrolls so fast and I never scrolled back up to the top.

I2C also appears to be broken in 2.5.5

Your latest update fixes the I2C issue as well. Looks like in 2.5.5 all sysex data was being parsed as strings.
