feat: prototype stronger typings

[Julusian]

Prototype of stronger action, feedback and preset typings.
This revealed a couple of missing/incorrect properties in the presets.

This is written fully generic, intended to be possible to reusable for other modules.

At the same time as this typings change, refactoring has been done to break up the excessively long files

This is largely just a typings change, with a notable change being done for the callbacks for actions and feedbacks. The options objects have been changed to be a class, which provides some methods. This allows for modules to simplify at couple of scenarios:

• getPlainNumber('myprop') allows for getting a number, and for verifying the property is a number. Internally it ensures it is typed as a number (parsing a string to number if necessary), returning the default for the property if it is undefined, and throwing an error if it is NaN.
• getParsedNumber('myprop') allows for parsing a string field, and converting the result to a number. This avoids needing to call parseVariablesInString explicitly, as that is done inside the functions implementation.

If this options class were adopted by @companion-module/base, it would allow for some better tracking of which properties are used by subscribe/unsubscribe, and would make supprorting button scoped variables simpler from the module side.

Upgrade scripts have not been touched.
