[Question] - does ros2 topic echo support multiple fields

[cwrx777]

Hi,

is it possible to echo more than one fields, e.g.

  ros2 topic echo /topic --field field_1 --field field_2

In the current code, it does not support this; it can only print out either the whole message, or a single field.

That said, I think it would be an OK feature to be able to select more than one. If you'd like to contribute a PR to implement it, we'd be happy to review it.
