Simple PTT GCC Compile Error + Possible Fix

[RobRich999]

SDRangel 9e51ace with Qt6 support enabled. Compiling with GCC 13.0.1 under Kubuntu 23.04:

/opt/build/sdrangel/plugins/feature/simpleptt/simplepttsettings.cpp:227:35: error: conversion from ‘const bool’ to ‘QChar’ is ambiguous
227 | m_rx2txCommand = settings.m_rx2txCommandEnable;

/opt/build/sdrangel/plugins/feature/simpleptt/simplepttsettings.cpp:242:35: error: conversion from ‘const bool’ to ‘QChar’ is ambiguous
242 | m_tx2rxCommand = settings.m_tx2rxCommandEnable;

I took a quick glance and made the following changes to complete the build:

m_rx2txCommandEnable = settings.m_rx2txCommandEnable;
m_tx2rxCommandEnable = settings.m_tx2rxCommandEnable;

Though I do not use the Simple PTT feature at this time, so I can not verify if the workaround.... well, works. ;)
