RON-1071 Ship "The Package", containing a portable version of RONIN

As the first major step towards making our entire product portable (meaning making it possible for people to actually "hold RONIN in their hands"), we would like to open-source a package named ronin, which effectively matches the programmatic signature of the current ronin package, except that the following must be ensured:

At the moment, RONIN only runs in the cloud, with the client being the main entry point into the cloud, since it serializes queries and sends them away, after which it receives a list of results to return from the client package.

Instead of requiring this interaction with the cloud, we would like to make it possible to run RONIN entirely standalone, such that anybody can run a RONIN database in the test suite of their application, in their migration script while testing changes, in a stateful application that would subscribe to the cloud version of RONIN, a local Electron app, or similar.

To accomplish this, we need to tackle all issues in Open-Source Data Layer, such that we can ultimately release a ronin package that imports the following logic pieces:

• The logic for converting RONIN queries into SQL statements.
• The logic for executing those SQL statements (the data layer).
• The logic for converting the response of the data layer into usable records.

Furthermore, the package must expose programmatic functions for updating the schema definitions of a local database, such that all actions (regardless of whether a developer wants to query data or modify schemas) can be taken through the client package.
