Fail if multiple transformation rules or bundles match the same license

[Vampire]

If you have org.hamcrest:hamcrest in your dependencies and use the LicenseBundleNormalizer with default rules, Hamcrest is reported as having both, 0BSD and BSD-3-Clause.

This is because for each a transformation rule matches. In this case even for different properties. There is an URL pattern that correctly matches the BSD-3-Clause URL, and then the name pattern BSD( |-)license.* which matches the name "BSD License 3" as 0BSD.

I needed quite some time to realize where this 0BSD is coming from.

Hm, I guess this will not really work out, as there could really be multiple licenses mentioned that should be taken into account, but the rules need to be changed.
