How is the data processed?

[oyarsa]

This repository doesn't contain the code to process the input data into the pickle files in the data folder. The paper says this:

Events are categorized into 20 main categories (e.g., appeal, demand, protest,
etc.) according to CAMEO methodology [59 ]. Each event is encoded with geolocation, time (day, month, year),
category, etc.

Is it possible to release the code to do the above or at least provide a high-level description of the process in the README? I'm especially interested in how you handled the GDELT data.
