[Suggestion] A better implementation for hiding EOB characters

By default, this theme hides the `~` characters at the end of a buffer and it seems to do so by setting its color to the same as the background. This method doesn't work well with transparent background, as there the `~` characters will still be more or less visible. Maybe a cleaner workaround would be to set the EOB filling character to a space. In Lua: ```lua vim.opt.fillchars = { eob = " " } ``` This has been working smoothly for me.
