Make a roadmap!

As @BcRikko said recently in #152:

Sorry, there is no roadmap. 😢

So I think we should change that! Let's discuss what other components we'd like to have added to the framework next. Once we have a list of components we want to add, we should create an issue for each component. Once that's done, we can add the good first issue label to each of them. That may encourage more contributors to come help us expand the framework.

So, here are the components that I'd like to see the most:

• <input type="range" /> (as mentioned by @BcRikko in #152)
• <code /> and <pre />
• <dialog />
• <kbd />
• <meter />

@nostalgic-css/nes-css and other contributors, what else would you like to see added to NES.css?
