Use: "addFilter",

Short: "Adds event filter to vulcanizedb",

Long: `An event filter is added to the vulcanize_db.

All events matching the filter conitions will be tracked
|
|
in vulcanizedb.

|
|
|
vulcanizedb addFilter --config config.toml --filter-filepath filter.json
|
|
|
|
The event filters are expected to match

the format described in the ethereum RPC wiki:
