parser/metadecoders: Add empty /data JSON file as empty map

Browse source 
When fetching JSON files from the /data folder that are empty they will
be added as empty map[string]any. This makes sure that no empty JSON
file causes the site to crash because of a failed unmarshal. This
happens because empty is not a valid JSON string. It is therefore
important to check the lenght of the data before passing it to the JSON
unmarshal function.

Fixes #8601
