The current json implementation in the stdlib does not support a
catchall like that. Also, you cannot embed a map in a struct.
You can replace JIRAFields with a map[string]any. If there are keys
with known structures, you can do a map[string]json.RawMessage, and
then you can do json.Unmarshal(fields[knownKey],&knownStruct) for
those keys whose structure you know.
Alternatively, you can use a map[string]any, and use the mapstructure
library to unmarshal a map[string]any to a known struct.
