fix: marko/compiler deprecation warning

[snyamathi]

Description

This PR switches from using marko/compiler to @marko/compiler, resolving the deprecation warning (below). There's a few things that I don't like about this PR, but lack the context to resolve quickly. I might need some help getting this over the finish line (cc @DylanPiercey).

However, the changes do work for me locally 🎉

⚠️ There is a reference to Marko 4 vs 5, so this might effectively be dropping support for Marko 4. I'm not sure of the support status of Marko 4 so this might need to be delayed until support for Marko 4 is dropped and/or major version bump this lib.

Motivation and Context

WARNING!!
Using `marko/compiler` has been deprecated, please upgrade to the `@marko/compiler` module.

This is definitely the biggest unknown; there is no compileForBrowser in Marko 5

[snyamathi]

concatMap.add(filename, code, map);

yields

Argument of type 'SourceMap' is not assignable to parameter of type 'string | RawSourceMap | undefined'.
  Type 'SourceMap' is not assignable to type 'RawSourceMap'.
    Types of property 'version' are incompatible.
      Type 'number' is not assignable to type 'string'.ts(2345)

@snyamathi thanks for creating the PR!

I'd rather keep it so that this module can support both Marko 4 and 5.
I will look into what's needed to do that, while getting rid of this deprecation message.

[snyamathi]

Absolutely - I was going to just raise an issue, but felt bad at least not attempting to see if I could do it myself.

Per tradition, I'll continue to ignore the warning for the time being 😆

Thanks for all the work you (all) do with Marko, much appreciated. Feel free to close this if you don't need it open for tracking.

@snyamathi I just did some project cleanup and improvements including this change over in #22.
This had been released as @marko/[email protected]. Let me know if you have any issues!
