Update LD Selector

[addie9800]

When working with Fundus I found that way too much JSON is extracted when computing the self.precomputed elements. This causes multiple issues:

• unnecessary but malformed JSON blocks cause avoidable crashes
• Additional JSON Blocks may cause irrelevant data to be extracted (e.g. the website (not article) author of the freiepresse test case: https://www.freiepresse.de/chemnitz/chemnitzer-hutfestival-wann-das-fest-steigt-was-neu-ist-und-wer-fuer-eine-gute-show-sorgen-wird-artikel13351201) All current parsers mention the type within their JSON, only the old version of TheNamibian did not follow that convention, hence the override.

To be honest, I would rather keep the generous LD selector and catch JSONDecodeErrors during parsing. You can fix the author for FreiePresse using get_value_by_key_path instead of bf_search .
