## Issue Addressed Add a new `--output values` option to `db inspect` for dumping raw database values to SSZ files. This could be useful for inspecting the database when we're unable to start the beacon node. Example usage: ``` # Output the `ForkChoice` column to an SSZ file lighthouse db inspect --column frk --output values ``` By default, it stores the output files in the current directory, and can be overriden with `--ouput-dir`. List of columns can be found here: https://github.com/sigp/lighthouse/blob/c547a11b0da48db6fdd03bca2c6ce2448bbcc3a9/beacon_node/store/src/lib.rs#L169-L216
