## Issue Addressed
Closes#2354
## Proposed Changes
Add a `minify` method to `slashing_protection::Interchange` that keeps only the maximum-epoch attestation and maximum-slot block for each validator. Specifically, `minify` constructs "synthetic" attestations (with no `signing_root`) containing the maximum source epoch _and_ the maximum target epoch from the input. This is equivalent to the `minify_synth` algorithm that I've formally verified in this repository:

## Additional Info
Includes the JSON loading optimisation from #2347
## Issue Addressed
Windows incompatibility.
## Proposed Changes
On windows, lighthouse needs to default to STDIN as tty doesn't exist. Also Windows uses ACLs for file permissions. So to mirror chmod 600, we will remove every entry in a file's ACL and add only a single SID that is an alias for the file owner.
Beyond that, there were several changes made to different unit tests because windows has slightly different error messages as well as frustrating nuances around killing a process :/
## Additional Info
Tested on my Windows VM and it appears to work, also compiled & tested on Linux with these changes. Permissions look correct on both platforms now. Just waiting for my validator to activate on Prater so I can test running full validator client on windows.

## Issue Addressed
Implements support for importing and exporting the slashing protection DB interchange format described here:
https://hackmd.io/@sproul/Bk0Y0qdGD
Also closes#1584
## Proposed Changes
* [x] Support for serializing and deserializing the format
* [x] Support for importing and exporting Lighthouse's database
* [x] CLI commands to invoke import and export
* [x] Export to minimal format (required when a minimal format has been previously imported)
* [x] Tests for export to minimal (utilising mixed importing and attestation signing?)
* [x] Tests for import/export of complete format, and import of minimal format
* [x] ~~Prevent attestations with sources less than our max source (Danny's suggestion). Required for the fake attestation that we put in for the minimal format to block attestations from source 0.~~
* [x] Add the concept of a "low watermark" for compatibility with the minimal format
Bonus!
* [x] A fix to a potentially nasty bug involving validators getting re-registered each time the validator client ran! Thankfully, the ordering of keys meant that the validator IDs used for attestations and blocks remained stable -- otherwise we could have had some slashings on our hands! 😱
* [x] Tests to confirm that this bug is indeed vanquished
* Implement slashing protection
Roll-up of #588 with some conflicts resolved
* WIP improvements
* Require slot uniqueness for blocks (rather than epochs)
* Native DB support for Slot and Epoch
* Simplify surrounding/surrounded-by queries
* Implement unified slashing protection database
A single SQL database saves on open file descriptors.
* Make slashing protection concurrency safe.
Revive tests, add parallel tests.
* Some simplifications
* Auto-registration, test clean-ups
* More tests, clean-ups, hardening
* Fix comments in BLS
* Optimise bulk validator registration
* Delete outdated tests
* Use bundled SQLite in slashing protection
* Auto-register validators in simulation
* Use real signing_root in slashing protection
* Update book for --auto-register
* Refine log messages and help flags
* Correct typo in Cargo.toml authors
* Fix merge conflicts
* Safer error handling in sqlite slot/epoch
* Address review comments
* Add attestation test mutating block root
