BREAKING CHANGES:

- Adopt Lightclient-protocol v0.4.0: PoolType filtering on CompactBlock,
  vin/vout fields on CompactTx, deprecate get_address_txids for light clients
- Rename CLI command 'run' to 'start'; config now at XDG path by default
- Migrate config system from figment to config-rs; cookie auth is now
  config-based; env var nesting uses double-underscore delimiter
- Move all workspace crates into packages/ subdirectory
- Remove local_cache/block_cache; all block retrieval via ChainIndex/indexer
- Rename crate core2 -> corez
- Make ZcashService a supertrait of Status trait
- Change ChainIndex trait parameters for consistency
