ENH: Add method to return CAMEO code description dataframe only about gdeltpyr

[smritigambhir]

Hi @linwoodc3 . Do you want the data frame to have all the fields present in cameoCodeTable.tsv file? If not, could you specify which ones you want or don't want? Also, in which file should this method be present?

@smweetee , I started this one and have it almost done. But, it will be a method just like Search but instead be called something else. I'll push tomorrow so you can see. The main thing I have to do now is include the descriptions for Version 1 events. I might as well add the dataframes for the other endpoints I'd like to hit.

I want to do the closed captioning GDELT data set (as a new table option) and the visual gkg. Will need to create issues for that.

Sure. Do tag me in the issues, when you create them :)
