Migrate from javax to jakarta XML Bindings #160
Description
Java 9 and later has external dependencies for JAXB support. However, current versions of these dependencies use the jakarta namespace, rather than javax, and they are therefore not compatible with regxmllib. In turn, regxmllib is not compatibe with Java host applications that depend on jakarta.xml.bind. See Netflix/photon#393, for example.
PR #158 resolves this issue.
