Version 1.10.3 is not compatible with Java 8 runtime

Trying to run a test with mockK 1.10.3 results in the following exception being thrown:

io/mockk/proxy/jvm/dispatcher/JvmMockKDispatcher has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0
java.lang.UnsupportedClassVersionError: io/mockk/proxy/jvm/dispatcher/JvmMockKDispatcher has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Downloading the mockk-agent-jvm-1.10.3.jar artifact from bintray, and running the following command confirms that JvmMockKDispatcher is using the Java 11 class file format (version 55):

javap -verbose JvmMockKDispatcher.class | grep version
  minor version: 0
  major version: 55

@OmarBeshary Use 1.10.3-jdk8 instead of 1.10.3.

Thanks for spotting this, going to run some tests and then release a Java 8 compatible version soon.
