Drop Data type `object`
According to @KatDwo, the object
data type was introduced at an early stage of the revised metadata by @mdolling-gfz who may add some details.
It does no longer serve any meaningful purpose, since limesurvey can not encode complex answer objects anyway.
The data type of questions that have answer options will be the one which the chosen option will be converted to.
Please adapt the metadata accordingly.
