Improvement request: Serialization Dataset to Json / Json to Dataset

[andre-f-m]

The great QuickLib already contain nearly everything to serialize from dataset to json (and back) which would be useful for transferring a dataset from server to client in JSON format. The tricky part is from JSON to DATASET as ideally it should create the field from a memory table. I had a quick look and Rest Dataware does have it (https://sourceforge.net/projects/rest-dataware-componentes/) but it is part of their component set and therefore it is linked to a lot of units and not straightforward to use it without their specific framework
