Another hiccup library.

This is a fork of Kevin Lynagh's fork of Hicada, which is a fork of sablono, which is a fork of hiccup.

Our approach:

Primary target is React (maybe support emit-to-string on Clojure down the road)
Do as much work as possible at compile-time, with graceful fallback to a fast interpreter (sometimes generating hiccup dynamically is worth it)
Be extensible within reason (extension points need to work across compile + runtime)

Features supported out of the box:

The :class key may be provided as a string, or vector of strings (joined at compile time)
Keyword tags may contain IDs and classes like so: :div#id.class-1.class-2
Symbol tags like [my-fn {}] are compiled to function calls, eg (my-fn {}). Children are untouched unless they are vectors that appear to be hiccup forms, in which case they are compiled.
Special tags:
- :el and :> compile to createElement instead of a function call (props & children are converted)
- :<>, :... and :Fragment resolve to react/Fragment.
- :Suspense resolves to a react/Suspense.
- :Portal resolves to react-dom/Portal
- a javascript array is passed directly to react/CreateElement without touching props or children
Props must be a literal map, or have ^:props metadata, eg. [:div ^:props foo ...]
