 *
 * `loader` will be called every time we encounter a source file. If it returns
 * a sourcemap, we will recurse into that sourcemap to continue the trace. If
 * it returns a falsey value, that source file is treated as an original,
 * unmodified source file.
 *
 * Pass `excludeContent` to exclude any self-containing source file content
 * from the output sourcemap.
 *
 * Pass `decodedMappings` to receive a SourceMap with decoded (instead of
 * VLQ encoded) mappings.
