Upgrade fast-xml-parser version from 4.2.2 to 5.5.7. This upgrade solves the dependabot issue of numeric entity expansion bypassing all entity expansion limits. This is a major version upgrade, so we need to confirm nothing is broken when testing. Also needed to fix an issue with X2jOptionsOptional and XmlBuilderOptionsOptional in the xml.ts file in order to accommodate the version upgrade.
