Add auto-export like mcchrish/zenbones.nvim? about lush.nvim

[rktjmp]

Probably:

• lush-template still ships with lush-loading theme.vim.
• :Lush export|print|out|save|freeze <fname> will:
  • Warn user we are making a work-flow destructive change (they will have to update config to load the "live" version")
  • Export the currently loaded theme to theme.vim in-between some markers
  • Disable lush-loading in theme.vim (probably just put the lush stuff inside the markers)
  • Export a fresh lush-loading theme to theme-lua|lush|live.vim (or copy the existing file at step 1)

This fixes a long standing pet-peev of mine where end user lush-themes generally require a runtime dependency (lush).

This may expand to a "lush transformers" set of functions, which savq has mentioned before. Probably external to the main repo (expected use by devs only), where it would provide say "lush-alacritty.lua" that takes a table and produces at least a buffer if not a file that can be used to theme alacritty.

This implies additional files that either run the exporter completely or at least define variables.

I just built out a very simple template building structure to zenbones.
Example template: https://github.com/mcchrish/zenbones.nvim/blob/main/lua/zenbones/build/alacritty.lua
Build script: https://github.com/mcchrish/zenbones.nvim/blob/main/lua/zenbones/build.lua

I copied a lot of ideas from melange and tokyonight.

The build script is just a wrapper of this simple string interpolation solution http://lua-users.org/wiki/StringInterpolation then write it out to the specified file path.

I got the luxury of having just a light theme so the implementation is quite simple.

Closing in favour #78 #77

Lua and lush are just too good. I can't stop writing more code. 😂
