Add evidence for dotnet components

[prabhu]

The code here reads the file contents and calls the utils method.

https://github.com/CycloneDX/cdxgen/blob/master/index.js#L3992

Instead, we rename parseCsProjAssetsData to parseCsProjAssetsFile and get the filename as the input. This could be later on set as evidence for the created packages.

Eg: https://github.com/CycloneDX/cdxgen/blob/master/utils.js#L390

evidence: {
  identity: {
    field: "purl",
    confidence: 1,
    methods: [
      {
        technique: "manifest-analysis",
        confidence: 1,
        value: pkgLockFile
      }
    ]
  }
}

Finally, fix the tests. Bonus points: Sort the components and dependencies list.

We're actively seeking new contributors.

@cerrussell is this implemented already?

@prabhu The sorting is... I thought the evidence part was, but now I'm not 100% on that. Will check tomorrow.
