Write a tutorial on UDFs to parse XDR in Hubble #1340

Description

@sydneynotthecity

What problem does your feature solve?

Hubble does not parse all data elements accessible in XDR. The platform does, however, save the raw XDR on the history_transactions table. This means that any element in XDR is accessible to end users. We should write a tutorial that shows people how to parse raw XDR and when it's appropriate to do so.

What would you like to see?

A tutorial and code stubs that demonstrate how to use the JS SDK in conjunction with BigQuery UDFs to access a data element that is available in the XDR, but not in Hubble's data schema.

@amishas157 has already backfilled data in Hubble using this method, so this should just organize some of her work and demonstrate that this is possible. This is an advanced concept that should live under Admin Guide > Data Curation or a Developer Guide

What alternatives are there?
