Feature Request: remove line and character position data from sourcemap

[pjebs]

Source maps are very large.
I only need the original filename (and original file path) for debugging stack traces.

There is an option to remove the sourceContent: https://esbuild.github.io/api/#sources-content

{
  "version": 3,
  "sources": ["bar.js", "foo.js"],
  "sourcesContent": ["bar()", "foo()\nimport './bar'"],
  "mappings": ";AAAA;;;ACAA;",
  "names": []
}

A good feature is to limit the mappings data to just the original filename and original filepath WITH no line number and character information (Or map everything to line 0 character 0 of a given source file)
