Langmap support in vim mode

[aeyquem]

In neovim, there is a feature called langmap that translates the keys in different modes (like normal mode) according to a map. For example, the neovim config looks like this: vim.opt.langmap="neoi;hjkl,hjkl;neoi"

this will make it so if i press cl" the editor will take it as ci" in normal mode, but not in insert mode.

This is extremely useful for custom keyboard distributions, specially the ones that are not dependant on the SO (like in custom keboards that have the distribution in the firmware, but the OS sees qwerty).
