further Improve parsing, rendering and build speed

[ECorreia45]

the rendering and parsing although fast enough, may benefit from some improvements especially when building.

Ideally, it would be great to have a

• better parser tailored for the type of HTML been written instead of using an HTML parser and then change the output before render
• decoupled render from parsing so the two can be better managed
• faster live rendering since it is just parsing string and SSR
• fast builder, especially when building templates per data list

a custom parser and renderer can also be used on the client-side for web components
