matrix_gpio
- persistency: the last frame of each digital and analogOut buffers is used to initialize all the frames in the next buffer. This means that once a value is set, the pin will hold the value until you change it
- AnalogXyz macros have been renamed to analogXyz
- the short option -P has been removed. The long option --pru-file has to be used instead
