Console spam when parsing inline sourcemaps

[apellerano-pw]

Problem

When this addon encounters an inline sourcemap (sourceMappingURL=data:application/json;charset=utf-8;base64,[giant base64 blob...]), it fails to parse it and generates a huge console message containing the entire base64 blob.

Cause

The source-map-url package used in this lib will return the entire inline sourcemap when you call getFrom(code).

This becomes an issue in get-sourcemap-content.js, because it always assumes getFrom(code) returns a url.

The filesystem exists check fails, and a console.warn message fires off saying the url referenced could not be found. However this url is actually the huge inline sourcemap blob!

[apellerano-pw]

As a workaround, you could exclude the file with the inline sourcemap from the ember-cli-terser config:

'ember-cli-terser': {
  exclude: [
    'assets/example.js',
  ],
},

According to the ember-cli-terser docs, it's okay to pass broccoli-terser-sourcemap config through it, and this lib supports an exclude globs array.
