* Better Infrared protocol file structure * Rename InfraredProtocolSpec to InfraredProtocolVariant * Slightly better names * Add repeat count field to protocol variant description * Repeat the signal the appropriate number of times when brute-forcing * Repeat the signal the appropriate number of times when sending via worker * Better signal count logic in infrared_transmit * Better variable names * Convert some raw signals to messages in tv.ir Co-authored-by: あく <alleteam@gmail.com>
