Minimal DOM primitives used by purescript-bonsai.

Bonsai programs use Elm's virtual dom, so the DOM is only needed for bootstrapping and side effects (like setting the focus, ...).

This provides wrappers for the needed functionality while taking care to be usable with JSDOM for testing.

purescript-bonsai is getting ready for 1.0. Once released, this package will be documented at https://pursuit.purescript.org/packages/purescript-bonsai-dom/
