## Issue Addressed
NA
## Proposed Changes
Add the Holesky network config as per 36e4ff2d51/custom_config_data.
Since the genesis state is ~190MB, I've opted to *not* include it in the binary and instead download it at runtime (see #4564 for context). To download this file we have:
- A hard-coded URL for a SigP-hosted S3 bucket with the Holesky genesis state. Assuming this download works correctly, users will be none the wiser that the state wasn't included in the binary (apart from some additional logs)
- If the user provides a `--checkpoint-sync-url` flag, then LH will download the genesis state from that server rather than our S3 bucket.
- If the user provides a `--genesis-state-url` flag, then LH will download the genesis state from that server regardless of the S3 bucket or `--checkpoint-sync-url` flag.
- Whenever a genesis state is downloaded it is checked against a checksum baked into the binary.
- A genesis state will never be downloaded if it's already included in the binary.
- There is a `--genesis-state-url-timeout` flag to tweak the timeout for downloading the genesis state file.
## Log Output
Example of log output when a state is downloaded:
```bash

Example of log output when there are no URLs specified:

The genesis state is not present in the binary and there are no known download URLs. Please use --checkpoint-sync-url or --genesis-state-url.
```
## Additional Info
I tested the `--genesis-state-url` flag with all 9 Goerli checkpoint sync servers on https://eth-clients.github.io/checkpoint-sync-endpoints/ and they all worked 🎉
My IDE eagerly formatted some `Cargo.toml`. I've disabled it but I don't see the value in spending time reverting the changes that are already there.
I also added the `GenesisStateBytes` enum to avoid an unnecessary clone on the genesis state bytes baked into the binary. This is not a huge deal on Mainnet, but will become more relevant when testing with big genesis states.
When we do a fresh checkpoint sync we're downloading the genesis state to check the `genesis_validators_root` against the finalised state we receive. This is not *entirely* pointless, since we verify the checksum when we download the genesis state so we are actually guaranteeing that the finalised state is on the same network. There might be a smarter/less-download-y way to go about this, but I've run out of cycles to figure that out. Perhaps we can grab it in the next release?
