Suggested pinouts

Hi again.

I suggest 2 more pinouts - combination of SWD + UART + FactoryMode detection and same for PIC. They're already presented in my libs. I use these combos in my projects, so I can get debugger, console and FactoryMode detection from single connector speeding up the manufacturing process and making R&D space cleaner. FactoryMode is just GPIO with pull-up, that is pulled down by the programming clip and makes the device enter init / test sequence after boot automatically.

Here are my pinouts:
PIN | SWD | PIC
1 - VCC - VCC
2 - GND - GND
3 - NRST - MRST
4 - SWDIO - PGD
5 - SWCLK - PGC
6 - RXD - RXD
7 - GND/FM -GND/FM
8 - TXD - TXD

As a markdown table:

| PIN | SWD   | PIC     |
|-----|-------|---------|
| 1   | VCC   | VCC     |
| 2   | GND   | GND     |
| 3   | NRST  | MRST    |
| 4   | SWDIO | PGD     |
| 5   | SWCLK | PGC     |
| 6   | RXD   | RXD     |
| 7   | GND/FM| GND/FM  |
| 8   | TXD   | TXD     |

For the SWD+UART version, why didn't you add the two UART lines into the existing SWD pinout. That seems far more sensible?
