USB PD 3.0 programmable power supply (PPS) support now available

Fun fact: initially, the PD Micro library and hardware were designed for USB PD 2.0 with fixed power output. Now, however, more and more PPS-supported adapters are available in the market. We purchased a USB PD PPS power adapter and did some quick code modifications to PD Micro. Excitingly, we've verified that PD Micro can run the PPS protocol without issues.
