Describe the feature you would like

#991 was closed by #1658, but as documented by this comment there's some other related work, so pulling that into separate issues.

---

Right now fuzz failures are only shown in the terminal, and there's no easy way to persist persist failures to allow saving them and easily re-running them.

• Enable FailurePersistance to /cache/fuzz/failures-latest.json.
• Add foundry.toml flag to specify outdir.
• Ensure proptest can use FailurePersistance to resume fuzz campaigns.
• Add --fuzz-input-file to allow user to specify a failures.json
