Add seeds.

[maflcko]

this fuzzer is only used to measure coverage of existing seeds. It can't be used to find new seeds because the seed format is fixed json

I theory it could find seeds that increase coverage, but that's both unlikely to find much (due to the strong format constraints), and not particularly interesting (as it won't have valid/invalid markers that match consensus, so it can't be used as unit test data).

Oh, I handle the fuzzing and the submissions automatically. The assumption I've operated under previously is that everything returned by find src/test/fuzz/ -executable -type f is worth fuzzing. I'm now excluding script_assets_test_minimizer.

I predict this is not the last time someone will waste time on fuzzing script_assets_test_minimizer (and then submit seeds for it) :)

Perhaps compilation of script_assets_test_minimizer should be opt-in? Or simply be moved to another directory?

Now excluding script_assets_test_minimizer seeds. Please re-review :)
