Nordic DFU OTA Compatibility

[zwells]

HCI_RX_BUF_QUEUE_SIZE must be 16 for Nordic DFU to prevent overflow

Solves Issue #63

[hathach]

Can you provide your set up inclduing app used, mobile hardware and os, bootloader, board and step to reproduce the issue so we could try to reproduce the issue first.

[zwells]

Any Arduino IDE generated zip package for Adafruit Feather nRF52832 bootloader can be given directly to nRF Toolbox, nRF Connect, or fengqiangboy/flutter-nordic-dfu (iOS and Android)

Hangs and fails on Starting DFU when HCI_RX_BUF_QUEUE_SIZE < 14

Succeeds when HCI_RX_BUF_QUEUE_SIZE >= 14

The issue with this is that changing the HCI_RX_BUF_QUEUE_SIZE = 16 generates the following error on make for Adafruit Feather nRF52832:
c:/program files (x86)/gnu tools arm embedded/8 2019-q3-update/bin/../lib/gcc/arm-none-eabi/8.3.1/../../../../arm-none-eabi/bin/ld.exe: region RAM overflowed with stack

This does appear to work for 52340-based boards.

I required this change for OTA DFU to work using nRF Connect on Android and a Sparkfun MicroMod nRF52840.
