segger RTT logger function for meshtastic that works with %i and floating point, it does use more stack etc

gistfile1.txt

// i added in DebugConfiguration.cpp

#ifdef USE_SEGGER

// largest string it can process
const int BUFFER_SIZE = 512;

/*********************************************************************
 *
 *  cx_SEGGER_RTT_vprintf
 *
 *  Function description
 *    Stores a formatted string in SEGGER RTT control block.
 *    This data is read by the host. Instead of using SEGGER_vprintf it uses the system one
 *    so that %i and floating point works
 *
 *  Parameters
 *    BufferIndex  Index of "Up"-buffer to be used. (e.g. 0 for "Terminal")
 *    sFormat      Pointer to format string
 *    pParamList   Pointer to the list of arguments for the format string
 *
 *  Return values
 *    >= 0:  Number of bytes which have been stored in the "Up"-buffer.
 *     < 0:  Error
