Proguard rules

To ensure the Kotzilla SDK functions correctly when using Proguard, declare the following rules in your Proguard file:

-keep class io.kotzilla.data.json.** { *; }
-keep class io.kotzilla.sdk.** { *; }

Additionally, if necessary, ensure to keep classes related to Ktor and Kotlin:

-keepclassmembers class kotlinx.** { volatile <fields>; }
-keepclassmembers class io.ktor.** { volatile <fields>; }
