* Simplify state snapshot test code
* Add raw data snapshot tests for the scanner
* Add snapshots
* Fix import path

* Upgrade the scanner database major version to 1
* Update format docs
* Change the high-level scanner db format
* Change the scanner serialization formats
* Fix value format and tests
* Fix incorrect types
* Update documentation

* Derive & impl helper traits from `std`
* Create `compact_to_v4` fn
* Create `fake_block` fn
* Refactor existing tests to use the new functions
* Cosmetics
* Refactor docs
* Put `Default` behind `cfg_attr(test)`
Rationale
---------
We avoid implementing `Default` on consensus-critical types because it's
easy to miss an incorrect use in a review. It's easy to hide a
`default()` in a call like `unwrap_or_default()` or even more subtle
methods.
