Minor suggestion: often I just want to extract one field, whose name I know exactly. I see that `jg` has an option `-F` like this:

$ cat sample.json | jg -F name

I would humbly suggest that a better syntax would be:

$ cat sample.json | jg .name

for a leaf node named "name"; or

$ cat sample.json | jg -F .name.

for any node named "name".
