READ_BUFSIZE should replace hardcoded magic number

[tedhenry100]

The reason for the following line is presumably to avoid reading off the end of packetbuffer.

if (replyidx >= 20) break;

Adafruit_BluefruitLE_nRF51/examples/cplay_neopixel_picker/packetParser.cpp

Line 83 in b80b880

if (replyidx >= 20) break;

In the case that the value of READ_BUFSIZE definition higher in the file is changed to a smaller number, the line would be safer and better if written as

if (replyidx >= READ_BUFSIZE) break;
