hm, seems like we can use an ENV var in the fuzzing call: rust-fuzz/cargo-fuzz#384 |

@elijah-potter would be nice to know what you think about this approach |

Description
this PR adds
cargo-fuzzfuzzing targets for harper parsers.Ideally, we wouldn't just fuzz the parser, but also the linting step with the resulting tokens to cover the
harper-corecode.Notice that I had to turn of
lto = truein the workpace Cargo.toml, so maybe we want to figure out how fuzzing can coexist with lto before merging.Related: #1898 #1948
