DataTemplating feature

Hi,

You have TextTemplating mechanism and this is very nice feature but this can be more generic.
My scenario:
I want to use TextTemplating pattern to generate Excel file or Word file.

If you rename Volo.Abp.TextTemplating.Core to Volo.Abp.DataTemplating.Core and change the ITemplateRenderer=>RenderAsync to return byte[] or Stream (not string), I can implement this interface and extend this feature to other file format.

Now I have created DataTemplating mechanism using the same pattern like TextTemplating to be more generic and I have implemented Excel Templating using Npoi and EPPlus and for Word I have implemented Templating using DocX and It can be also implemented using Npoi Word.
I use the same language syntax like scriban / https://mustache.github.io/

If you want I can share this code implementation with you.
I wait for your feedback about this change/feature.
Thanks
