686b605112 Pretty-print EIP-3076 tests (#1977)
## Proposed Changes

* Pretty-print the EIP-3076 tests to match https://github.com/eth2-clients/slashing-protection-interchange-tests/pull/4
* Move the `curl` invocation that downloads the tests to the test executor, removing the build script (closes #1982)

20339ade01 Refine and test slashing protection semantics (#1885)
## Issue Addressed

Closes #1873

## Proposed Changes

Fixes the bug in slashing protection import (#1873) by pruning the database upon import.

Also expands the test generator to cover this case and a few others which are under discussion here:

https://ethereum-magicians.org/t/eip-3076-validator-client-interchange-format-slashing-protection/4883

## Additional Info

Depending on the outcome of the discussion on Eth Magicians, we can either wait for consensus before merging, or merge our preferred solution and patch things later.

1d278aaa83 Implement slashing protection interchange format (#1544)
## 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
