Use DRAM for ESP32 protocol list and replace ICACHE_RAM_ATTR by IRAM_ATTR for ESP32, so as to avoid core dump when using in conjunction with Wifi
Added support for Holtek's HT12E encoder/decoders
Added 1ByOne Doorbell protocol
There is a tiny bug hat prevents the usage for "Conrad RS-200" based devices. The RS-200 protocol does not repeat packets that often. One need already to detect the end of the first packet. The gap between two transmission are not handled right when RF packet is received first time.
a) 1st gap detection fixed
b) Furthermore the "Conrad RS-200" protocol is added.
