Added ADC/DAC resolution to $pinstate command, changed reported values to integer for ADC/DAC devices and float formatted for PWM devices. Numeric settings can now be set via G65P1Q<n>S<value>, <n> is the setting number, <value> is the new value. Changed alarm code for Modbus exceptions (communication errors) from 14 to 19. Refactored MPG stream code to allow plugins to hook into MPG streams (via event handler). Added _free memory system parameter, returns value in KBytes or -1 if not available from driver. Changed basic stream data type from char to uint8_t, added HAL function and core API for releasing/closing UART streams.
