Fix usage with raw loader

[mistic]

That should fix #68

Could it be better if we use base64 for raw data encoding to reduce the cache file size ?

@malash thanks for the suggestions. I had them in account on the last changes 👍

LGTM Thanks!

[alexander-akait]

Looks good 👍

Just question: maybe we can use serialize-to-js package, it is support many types and in theory loader can return non buffer and non string (yes it is not used in real life and not good idea, but it it possible)

@evilebottnawi it could have been an excellent solution but after trying that serializer-to-js I found performance penalties. I think we should stick with buffer-json for the time being 😃
