Vite compatibility

[aerotoad]

The current system is using Vite for building the library and Parcel for serving examples during development.
The Xeito CLI creates a new application using only Parcel configured to use TSC by default.

Testing and exploration of different vite configurations to create a standalone application always result in different features not working as intended.

Most of the time this is due to the lack of support for typescript experimental decorators and even using Babel things get really messy really fast.

Creating this issue to keep track of it since the new TC39 decorator proposal might arrive at esbuild (feature request) in the near future and this could open the door for vite compatibility.

It should be possible to create a vite plugin to use the ts compiler before esbuild.

It's now possible to create a Xeito application with vite by using @xeito/vite-plugin-xeito
