Simpler reconfiguring

From https://discourse.julialang.org/t/ann-replsmuggler-jl-send-code-to-your-julia-repl-and-get-neo-vim-diagnostics-in-return/111420/2

With vim-slime I often reconfigure the target window (e.g. two Julia REPLs with different Julia versions running). I have it configured so that :SlimeConfig automatically targets the last visited tmux pane. I see that you can reconfigure also with REPLSmuggler but you then have to remember which socket belong to which pane etc. It would be great to make switching like this easier.

Concretely, just having an option to specify the socket name in smuggle might be enough. Then I would simply configure it such that the name was something like tmux-1 or whatever which would make it much easier to select from neovim. Perhaps this could be done automatically when detecting a tmux session even.
