Tasmota: Support Wiegand 26 reader

Possible maybe ;-) At the moment not supported

RFID readers requested at #2915

i think that wiegand-protocol for NFC-reader is not the same as PN532 reader.
i have fingerprints with Wiegand-interfaces, and also NFC-Reader combis.

i would love to see this in tasmota. maybe together with the pn532?

could be easy coded, i guess, it is almost done on espeasy.
maybe some developer has a ❤️ and copy and paste the important bits over to tasmota 😄

wiegand lines here on espeasy-source on github

event->String1 = formatGpioName_input(F("D0 (Green, 5V)"));
event->String2 = formatGpioName_input(F("D1 (White, 5V)"));

get wiegand data simply from interrupt here on espeasy-source on github
