Before merging in the oss-fuzz corpora from Google, there are some changes to the fuzzer. - Add a read corpus script, to display corpus files nicely. - Change the behaviour of the fuzzer so that TLV parse failures all now go down the same execution paths, which should reduce the size of the corpora. - Make unknown TLVs a failure to parse, which should decrease the size of the corpora as well. Closes #1881
