* infrared: add Kaseikyo IR protocol Add Kaseikyo IR protocol support. This protocol is also called the Panasonic protocol and is used by a number of manufacturers including Denon. The protocol includes a vendor field and a number of fields that are vendor specific. To support the format of address+command used by flipper the vendor+genre1+genre2+id fields are encoded into the address while the data is used for the command. There are older versions of the protocol that used a reverse bit order that are not supported. Protocol information: - https://github.com/Arduino-IRremote/Arduino-IRremote/blob/master/src/ir_Kaseikyo.hpp - http://www.hifi-remote.com/johnsfine/DecodeIR.html#Kaseikyo - https://www.denon.com/-/media/files/documentmaster/denonna/avr-x3700h_avc-x3700h_ir_code_v01_04062020.doc * Format and add unit test to Kaseikyo IR codec.
