Add standardization of frameworks

[sgjohnson1981]

Would be great if this was in table format, with a standardized number of columns that represent aspects of the frameworks. For example, many of these don't support open-source models, only OpenAI's offerings. Would be great if I could quickly see which ones do or don't.

@tizkovatereza sorry for the tagging, but I noticed there's not much activity here so just making sure....
