Support for multiple programmers

[sq6sfo]

Currently stm8flash is using libusb_open_device_with_vid_pid function that returns handle to the first device that match vID and pID. I've created a simple patch that adds -S option that allows for specifying the desired programmer. I have some difficulties creating pull-request so feel free to use my change if you find it useful.

I can also confirm the tool works flawlessly for target stm8l151?6 (STML151G6 in my case) multiple.diff.gz

Can You give an example of use (format of serial)? How do You get serials of STLInks? For the moment I use st-info --probe from texane st-link. Btw.:

As far as I know st-info uses similar format of the serial number. Basically I'm using the iSerialNumber string from libusb device descriptor. I then directly print the char values in hexadecimal uppercase format (some characters in iSerialNumber string are not printable and would be hard to copy-paste). Example serial of my stlink-v2-clone: 543F7206757757493431123F

@PanKaczka I think that's the case:

        else  **//<-- no { here**
            // otherwise check if it's the correct one
            if(0==strcmp(serial_hex, pgm_serial)) {
                pgm->dev_handle = tempHandle;
                break;
            }
        }
