"make fuzz" creates a simple executable that de-serialises stdin
and re-serialises to stdout.
"make fuzz_testcases" extracts the smaller json test cases into
a testcases directory.
The library can then be fuzzed as follows:
CC=afl-clang-fast make fuzz
make fuzz_testcases
mkdir out
afl-fuzz -i testcases -o out ./fuzz
