[Feature] Command for switching back and forth between the REPL window and editor

[PEZ]

Slightly related to #337

I'd like a command that allows for switching back and forth between the editor and the REPL window. Like so:

• If I am editing a file, the command will
  1. Open the REPL Window.
  2. Switch it to the namespace of the file.
  3. Give it focus.
• If the REPL window has focus, the command will:
  1. Open the file corresponding to the current namespace of the REPL window.
  2. Give it focus.

Clojure files should open the CLJ REPL Window. ClojureScript files should open the CLJS REPL Window. CLJC files should open whatever REPL window corresponds to the current mode backing the file.

It might need to be implemented using several commands with the same keyboard shortcut and intelligent enablement and when clauses.

@PEZ Now I understand what you mean. gg

C-c C-z in Cider, FFIW
When you're in the REPL-window, this keybinding calls cider-switch-to-last-clojure-buffer, when you're in a clj/cljs buffer, it calls (cider-switch-to-repl-buffer &optional SET-NAMESPACE)

Can't believe this hasn't been implemented... Do you guys click back and forth between REPL and Editor with a mouse?

@CasualGitEnjoyer Speaking for myself, I very rarely type in the repl/output window. Most of my repl workflow happens from the editor.

However, this can actually be achieved at least somewhat by using the command for opening the repl window (which focuses it), and using the Go Back command to go back to the last editor.

This is actually mostly implemented since long. Bound to ctrl+alt+o o by default. But VS Code's API makes it impossible to implement the reverse (from REPL window to the file) in a very nice way (very often we just open a new editor with the file instead).
