If TouchOSC /ping enabled, Synergize may crash

[chinenual]

Synergize does not properly filter messages TouchOSC can be configured to send (/accxyx, /z and /ping). This results in messages such as the following in the log:

2020/11/06 20:20:03 ERROR:  SendToUI failed to decode json response : accxyz 0: unexpected end of JSON input

In my testing I was able to crash Synergize by flooding it with /accxyz accelerometer messages; others have reported network related errors (e.g. CONNRESET) which may be related. See #14

Until fixed, workaround is to ensure that these are disabled in TouchOSC (Options->OSC-> all toggles should be off)

Fixed for version 2.2.1. Added a blacklist filter to ignore /ping, /accxyz and /z messages from TouchOSC

FWIW, it appears that the crash was caused by /ping messages from TouchOSC -- the accelerometer and touch messages are "harmless" (?), but flood the logs with errors and cause unnecessary traffic between the app and the UI
