classification example to freertos with cpx

[knmcguire]

These are efforts to move the classification example to freertos and run CPX debugging instead of printf.

There is still an issue though, as it blocks after the first cpx debug to console. After GAP8:" *** Classification ***" I don't see "Starting to open camera". So it's blocking in between somehow?

This line needs to be changed too which might interferes with the wifi example

This needs to be changed to

#define TXQ_SIZE (80)

There seems to be some cpx handling that needs to be changed first. See this issue: bitcraze/aideck-esp-firmware#9. Or we have to make a different initialization function for CPX where we can define the size.

Or we should pick a smaller network than mobile netv2 just for the example, or try to see if we can reduce it further with quantizing the network even more? We need a bit more space for cpx to work :)

Looks good, just some small stuff with formatting.
