Build a cross-chain model

[RafaelAPB]

Build a cross-chain model using Hephaestus and the exported transactional data. This includes refactoring/using the Python code from Hephaestus. This integrate Hepheastus with SATP. SATP should create an instance of Hepheastus to create the model and do the monitoring in a later issue.

Requirements:

1. Obtain transactional data from the created cross-chain model endpoint.
2. Create a pipeline (Python, TS) that calls that endpoint and builds a cross-chain model from the provided data
3. Create a pipeline that updates the cross-chain model with the data from that endpoint from time to time
4. Create support scripts to automate the pipelines
