Allow DataPopulator to populate artboard names
**Which version of the plugin are you using?**
[x] Data Populator for Sketch
[ ] Data Populator for Adobe XD

**Is your feature request related to a problem? Please describe.**
I have a JSON file with 1200+ Icons and Keywords and would like to make a symbol library of them in Sketch. However, the symbols should be named using the Keywords so that they are searchable; but DataPopulator does nothing with the {Keywords} in each artboard (symbol master) name.

**Describe the solution you'd like**
It would be great if DataPopulator could also recognize and change tagged { } artboard (symbol master) names.

**Describe alternatives you've considered**
I'd have to go in and title each and every one of the 1200+ symbol masters with the Keywords by hand =(
