Specify default query

[pavelzw]

It would be cool to be able to specify a default query for interactive searching:

$ cat data.json | jnv --default-query '.result.abc'
❯❯ .result.abc
...

This would make it easier when inspecting multiple similar json inputs to always land in the same entry and investigate interactively from there using jnv instead of needing to type .result.abc each time.
