feat(drift): add from_cli constructor and add docs

[tachyonicClock]

• Add doc strings to drift detector creation. This was done using an LLM. I did ground the documentation using the MOA source code so I reckon it should be okay.
• Rather than using Detector(CLI=...) this is now written as Detector.from_cli(...). The main constructor is just for arguments Detector(delta=0.1). This gives users one way to do each thing rather than one way to do two things. I can imagine someone overriding their parameters with CLI= or being confused when it used MOA defaults instead of CapyMOA defaults. I also simplified some constructor logic. I'm considering using a similar pattern for classifiers as well, if we like it.

@vcerqueira does the first commit break anything for you?
