Feature request:
xterm.js is extensible via addons. Hyper currently loads a static set of addons (https://github.com/zeit/hyper/blob/bad51f9c15a9f094588a3c3e36bea2b5151d4606/lib/components/term.tsx#L154-L158). It would be useful to allow plugins to enable additional addons.

One of the main motivators behind this would be to allow for custom ILinkProvider to enhance user interaction with text objects. Some examples of link providers beyond the static WebLinksAddon could be matching emails or user provided regexes as requested in xtermjs/xterm.js#2893.
