Feature request: Expand macro recursively

[edwloef]

I'm not sure whether this is useful in many languages besides rust, but seeing macro-expanded code can be useful at times. Having an editor command/action to do this with the macro the cursor currently resides in would be useful.

This is how Zed does it:

From what I can tell this feature is just a wrapper around cargo expand {function name}. If so, I'd say this could be marked a duplicate of #67. The shell command should be specified to include a way to send the current selection (or word-at-cursor) to the shell command and also a way to specify that the output should be sent to a new buffer (and allow specifying the language).
