It would be nice to mention that only Java 17+ is supported

Hi! Thank you for the library!

I just right now decided to check this library, but unexpectably got an error that JVM classes are compiled with more recent version of Java than Java 11. It would be nice to mention in README that it supports only 17+ versions of JVM.

Hi @lounres! Thanks for reporting that!

I'll probably change the compilation down to Java 11 to support more cases like yours.
