Adds features to eqx query ... cosmos:

• -C: emit query output to Console
• -o/--output filepath: emit CR-delimited JSON showing raw query output
• -P: pretty print the output indented over multiple lines
• -m/--mode raw: SELECT * from matching docs (and show ages)
• -sn: specify exact stream name instead of category name or category pattern

Example use cases:

• Useful complement to eqx dump for troubleshooting (eqx query focuses on the raw JSON and uses CosmosDB queries; eqx dump does a read Equivalent to an application-level Query call)
• Great for gathering event counts/RU cost stats for tuning/sanity checking
• Also useful for shuffling categories or streams between stores for inspection and/or doing general things that you do via SELECT INTO hackery in SQL stores
• the propulsion-indexer template's upconvert and sync commands and/or the propulsion-sync templates can be used to import and/or upconvert based on such dumps (NOTE they can of course also identically work from the changefeed)
