Android 14 Migration

Hello @Kurumi

I am facing error shown below in Android 14 devices. This is due to new Android 14 behavior changes. I have attached the error causing line in GXSerial.java (gurux.serial.android/Java/Serial/src/main/java/gurux/serial
/GXSerial.java) (check 1 in attached image). Please consider making changes to similar code.

Error --> One of RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED should be specified when a receiver isn't being registered exclusively for system broadcasts.

Additionally, please downgrade the version of androidx.appcompat library to 1.6.1 from latest release (1.7.0) if the latest version is not crucial to upgrade. We were facing a lot of issues due to this. We had to make workaround and exclude latest(1.7.0) dependency and run library on 1.6.1 manually. (check 2 in attached image)
