CLI flag to 'open editor' on launch

[fresh2dev]

Is your feature request related to a problem? Please describe.

Today, I open mods, then press ctrl+e to open my editor. I do this every time I open mods. And I most often open mods from within my editor (vim / neovim).

Describe the solution you'd like

Please add a CLI flag like mods --editor that will launch an editor and feed the saved text into mods.

Describe alternatives you've considered

A shell alias / function like:

tmp_file=$(mktemp) && vim $tmp_file && cat $tmp_file | mods
