Metafile is now inaccessible

In the last version, the metafile field changed from a string to a boolean which causes esbuild to not produce the metadata as a file as it was previously doing. If I understand correctly, the BuildResult is now missing a meta field containing this data.

Thanks for raising, I've added the field now to the output, it should be available in 0.13.8. Let me know if it works on your end.
