Can transparency be applied?

[nappalm]

I don't see any properties that allow configuring the theme with transparency.

There isn't an option at this point in time. You can get most of the way there by doing something like this

vim.cmd("colorscheme embark")
vim.cmd("hi! Normal guifg=NONE")

This won't handle things like popups, statusbars, or gutters but I feel like its pretty passable. This is why I haven't added an option yet.

If you end doing a more complete transparency setup and feel up to a contribution I would be willing to merge an option.
