Aliexpress buzzer is active not passive #219

Closed gmbuell closed 1 year ago

The buzzer on Aliexpress linked in the readme is a 5v active buzzer. The tagreader.yaml calls for using the ESPHome rtttl component which is supposed to be for passive piezo buzzers. 3V would also probably be more appropriate than 5v since the logic level of the D1 is 3.3V
