attempting to modernize dev_server

[bunnybones1]

Hey there,
I have a need for something much like what you've written here.
I made a few edits to make it run against the latest deno/std and abc
It seems to work fine but I'm not entirely sure to be honest (I usually just do front-end dev and graphics)

Futhermore, I'm trying to get sourcemaps to work but it looks like CompilerOptions don't do anything with sourceMaps or inlineSourceMap
In fact most of the CompilerOptions I tried made no difference to the output.
I wonder if I was doing something wrong.

Thank you very much for spending time on this. Deno has changed a lot during this time, I will try your patch right away.

Sorry not supported (denoland/deno#4499)

Thanks for confirming that. I hope that gets addressed in the near future.
Until then, I suppose productive development without source-maps is possible, but it's a different mindset :)

Anyway, thanks for your pr
