Cleanup logging

Initiate our Volume Change down after call using TEL as source for IBUS, bypassing our volume management handlers.

Simplify volume offset calculations. Fix unusual logic in PCM51XX volume management.

Add detailed logging around volume changes when calling.

[IMP] firmware: Application 1.3.2 * Downgrade toolchain to 1.70 to resolve Address errors * Set _ADDED_C_LIB as a global define. This option adds snprintf() and vsnprintf() * Add more consistent method of writing the BC127 boot failure count * Default log buffers to 0x00 * Resolve buffer overflows in UI code setting values one address off from the end of the array

[IMP] firmware: Application 1.3.2 * Update to toolchain 2.0.0 * Prevent RPOR (Reprogrammable pin) memory overflow by not reading registers above 15 * Prevent memory overflow caused by writing more timer tasks than are available * Add Error level warning if more timers are being assigned than there are slots for * Fix UART RX Register Reset issue when a frame error exists by reading the register directly, rather than the pointer to it * Resolve issue logging BC127 boot failure by directly calling EEPROMWriteByte so that the value is not ignored * Various `volatile` keywords to ensure there are no unwanted optimizations where required

Make sure we support response without space in front of time field
