Add multiple slave selects and Data/Command signal for SPI analyzer

Add multiple slave selects and Data/Command signal for SPI analyzer

At the moment there is only one Enable signal for SPI. I would like to see at least 3 enable signals in case multiple sensors and devices are connected to one SPI channel. Optionally, I would like to have Data/Command signal to allow triggering with the command byte value.

These ideas can be seen in this tutorial page http://www.emblocks.org/wiki/tutorials/f401_f429_disco/spi.

    You can create multiple spi analyzers for this. The signals are grayed out to show that they are in use, but you can still select them. Only trouble is, you now have analyzers "SPI" and "SPI." Currently I set one analyzer to spit out hex, one dec, and one binary to distinguish between my 3 spi devices.
