Performance bottle neck in DataHandler.Handle* methods

[ahmed-shariff]

I am running a few experiments that require tracking a large number of objects. This results in the SaveData method taking a lot of time to process all the data, which influences my results. I had touched on this in a previous PR (#143 ). Upon further digging, I ended up wrapping the calls to SaveDataTable in a task, which resulted in as much as x20 improvement in the time taken to process the SaveData method.

I have a rough working version of this in a fork I am maintaining as a package: ovi-lab/UXF-extensions@2c3f753

Let me know if this is something you may want to consider merging upstream.

Amazing! Sorry I don't have much capacity to actively work on UXF. But feel free to submit a PR if you like, and I can check it out.
