fuzzer-parse_json_view.cpp checks for every input that
json_document::accept agrees with json::accept, that an accepted input
materializes to the value json::parse returns, and that a rejected input
makes both throw the same exception with the same message. It is built
like the other fuzzers (tests/Makefile, and the root Makefile's
fuzz_testing_json_view target, which starts from the JSON test corpus) and
listed in tests/fuzzing.md.
