Also read `license-mapping-override.json` to allow overriding license mapping

Personne n'a encore pris cette issue.

Change the code for [resolveFuzzyMatching()](https://github.com/CycloneDX/cyclonedx-core-java/blob/8a4d83e05889373024c3ea7ef1f630b35394e7ae/src/main/java/org/cyclonedx/util/LicenseResolver.java#L160)

In addition to `license-mapping.json` also read `license-mapping-override.json` and use the values from this file with priority.

This will allow end users to define their own mapping.
You can easily override the classpath in [Maven](https://github.com/jakub-bochenski/example-cyclonedx-core-java/blob/master/pom.xml#L51-L61) or Gradle.

Right now I'm building my own fork of `cyclonedx-core-java`, but I'm only interested in changing this file.
Allowing users to just provide this file on the classpath would be much easier than having to rebuild the whole library.

ATM I could just copy the `license-mapping.json` and change it and provide on the classpath, but
- it easily gets out of sync with upstream
- classpath order can be problematic

Commencez dans src/main/java/org/cyclonedx/util/LicenseResolver.java, au niveau de resolveFuzzyMatching(), et examinez comment license-mapping.json est chargé. Ajoutez la prise en charge de license-mapping-override.json en donnant la priorité à ses valeurs, puis vérifiez les tests existants du projet ou sa suite de tests. Le travail est terminé lorsque les utilisateurs peuvent fournir la ressource d’override sur le classpath sans reconstruire la bibliothèque.
