Include analog device presets

[diego-plan9]

Description and motivation

While using the family of RPUConfig devices and adjust their parameters manually offers a great deal of flexibility, for some use cases being able to start with a set of pre-defined interesting configurations would be useful. This would help the users being familiar with the different options, serve as a basis for exploring the toolkit, and allow using "well-known" configurations off the shelf for a number of purposes.

Proposed solution

Add a number of curated analog device presets to the package, representing devices in existing literature or other specific configurations that seem relevant or interesting.
