LTI Extension Asset Processor

https://github.com/1EdTech/LTI-central/blob/main/proposals/asset-processor/specification.md

The asset processor profile is a collection of LTI extensions that when implemented and used together, provide the optimal user experience and allow for the richest possible asset processor integration. The individual extensions used in this profile may be implemented in isolation, however this may lead to a degraded user experience, increased manual configuration during setup or reduced interoperability.

The aim of an asset processor is to provide an integration by which assets (documents, videos, text, files etc.) that are submitted to an LTI platform can be processed by a tool and have a report returned by the tool to the platform. The extensions are designed to allow for the easy configuration of one or more processors on a variety of activity types.
