Update Parcel to v2

[DaVince]

The current version of Parcel is based on 1.x and does not seem to be maintained any longer. This is now leading to some higher severity security issues by using it.

I'd like to switch to v2 but the biggest roadblock in moving right now is the fact that I do not know how to bundle assets without having to refer to them in a ts file. The current version manages this by using a plugin that simply copies over the entire assets directory as-is. If someone has experience dealing with this kind of asset management and knows how to do it in Parcel 2, the help would be appreciated!

On another note, I use esbuild myself these days for the incredibly fast build time, but there too I am currently dealing with copying the assets over manually. Unfortunately copying them over manually does not seem to be a functional option for Parcel 2.
