the class EnumSyntaxChecker calls a old version of jackson-coreutils JsonNumEquivalence

[SimonePDev]

Hello there, you release awrong version of a class: in com.github.fge.jsonschema.core.keyword.syntax.checkers.common.EnumSyntaxChecker you call the class com.github.fge.jackson.JsonNumEquivalence that is not supposed to be in the other library since it has been changed to JsonNumEquals.
can you fix this?
