feat: add detector experiments

[melotic]

This adds the ability to conduct experiments on a set of detectors, allowing us to compare the detected components of detectors.

We take diffs of the components with respect to:

• Component IDs
• Root components
• Is a development dependency

The output diff is serialized to a JSON model and written to disk. A future PR will send this data as telemetry.

Current Experiments

Nuget Detector

Control Group: NuGetComponentDetector and NuGetProjectModelProjectCentricComponentDetector
Experimental Group: NuGetPackagesConfigDetector and NuGetProjectModelProjectCentricComponentDetector

NPM With Roots Detector

Control Group: NpmComponentDetector
Experimental Group: NpmLockfile3 detector.

👋 Hi! It looks like you modified some files in the Detectors folder.
You may need to bump the detector versions if any of the following scenarios apply:

• The detector detects more or fewer components than before
• The detector generates different parent/child graph relationships than before
• The detector generates different devDependencies values than before

If none of the above scenarios apply, feel free to ignore this comment 🙂

Only tiny comments on naming. Otherwise, looks good. Approving so as not to block.
