[R/writeData2] add hash_id for formats

[JanMarvin]

The idea is solid, the coding still needs improvements.

I have tried to avoid calling and creating the same formats by adding some hash string. This might blow up the number of formats, but it shouldn't really matter for us. Unfortunately it didn't fix that initial error.
