Having proguard enabled interferes with this library

[mateogianolio]

I'm not sure what proguard does, but it interferes with this library and causes error when creating a session (e.g. before scan wifi list).

If someone still needs this, try with this:

-dontwarn com.espressif.provisioning.**
-dontwarn espressif.**
-keep class com.espressif.provisioning.** {*;}
-keepclassmembers class com.espressif.provisioning.** {*;}
-keep class espressif.** {*;}
-keepclassmembers class espressif.** {*;}
-keep interface com.espressif.provisioning.** {*;}
-keep interface espressif.** {*;}
-keep public enum com.espressif.provisioning.** {*;}
-keep public enum espressif.** {*;}
