Swap Front and Back Mics

Here is the required I2S configuration to set the channels correctly:

AudioConnection_F32           patchcord1(i2s_in, 1, inputMixerL, 0);  //Left-Front Mic
AudioConnection_F32           patchcord2(i2s_in, 0, inputMixerL, 1);  //Left-Rear Mic
AudioConnection_F32           patchcord3(i2s_in, 3, inputMixerR, 0);  //Right-Front Mic
AudioConnection_F32           patchcord4(i2s_in, 2, inputMixerR, 1);  //Right-Rear Mic

Here is the desired I2S configuration:

AudioConnection_F32           patchcord1(i2s_in, 0,	//Front-Left     
AudioConnection_F32           patchcord2(i2s_in, 1,	//Rear-Left  
AudioConnection_F32           patchcord3(i2s_in, 2,	//Front-Right  
AudioConnection_F32           patchcord4(i2s_in, 3,	 //Rear-Right  

To achieve this, the front and rear mic need swapped (which means changing what the select lines are connected to). See changes in RED.
