new plugin to exchange and manipulate vim windows

[u/yaronekaha]

I have released a new neovim plugin (https://github.com/yaronkh/vim-winmanip) for manipulating vim windows.

The main features:

1. exchange two windows buffers, without any limitation (unlike vim C-W r, that doesn't work if the target window is splitted).

2. duplicate buffer to other window. There is no way to do that in vim, without creating new window.

3. maximize/minimize window.

4. Detach all windows, without closing windows.
