Add missing output formats and upgrade dependencies

[hjrgrn]

Changes:

• Add missing formats for the --output flag: short, json, json-N, bunyan.

• Add test case for this functionality in a new file.

• Upgrade all dependencies, migrate to colored 3 and predicates 3, add "preserve_order" to serde_json in order to obtain an order of the output fields coherent with node-bunyan.

• Add minor improvements: removing trailing white spaces, removing clippy warnings, etc...
