Testing I/O board flashing

TIAB flashing testing tool

We assume that the flashing process was successful if:

1. The vendor and product ids of the FTDI devices are correct
2. SMT32 replies to an empty command with a correct prompt

The TIAB testing tool performs these checks automatically in the following order:

1. Firstly it iterates over all Codethink USB devices and checks all of FTDIs for presence.
2. If it is not able to find the one of the FTDIs, it looks for unflashed FTDIs in the system and prints them out.
3. After testing the FTDI devices, it checks if the STM replies to an empty command with a correct prompt.

To run the TIAB testing tool, run tiabtest in the project directory.
