v0.5.0

update lume/variable and solid-js with support for better ESM standards defined by Node

This is a breaking change because the new JSX/template support is in solid-js 0.24
has some API modifications. Components made
with this version of lume/element may not be interoperable with those
made with a previous version of lume/element because compile output will differ and will be
using slightly different APIs from solid's runtime. End usage hasn't changed.
