fix occasional issue with cell reuse when avoiding updating cells during table size estimation

* Replace ZBar JNI library implementation with jzbar

* Move ZBar.java to com.sparrowwallet.sparrow.control package

* Move ZBar.java to the com.sparrowwallet.sparrow.io package

* Switch to jzbar from Maven Central and update module/package imports accordingly

* Remove jzbar entry from extraJavaModuleInfo to avoid module patching error
