Encode: DecodeHook not called for struct fields

I use the DecodeHook to translate the values of certain fields. This works great when "decoding" from map -> struct, but doesn't work the other way around.

When I "encode" from struct -> map, the DecodeHook is called only once, for the whole struct. I would expect it to be called for each field as well.

I've currently hacked it into my decoderHook function, by iterating over the fields and recursively calling itself. But this is rather tedious and has the disadvantage that I can't change the types of fields.
