Hotfix: Missing function "sanitize_package"

[ScreamingDev]

As reported by a user PHP throws an error and complains about a missing method. Instead of removing the wrong code the method has been introduced here. This means duplicate code but fixes another number formatting problem at the moment.

What has changed?

• Introduced missing method.
