Bug: Binding-Scripts get generated for Packaged UXMLs

[siglocpp]

I found an interesting bug, while generating some new UIs:
Rosalina somehow generated Binding Files for some pre-packaged uxmls inside of the unity-core. (see Screenshot).

I'm not quite sure how to reproduce this issue, but it happened to me now twice, after restarting unity.

I think, we need something like a Path-Filter on which uxmls to interprete, to prevent things like that from happening.
I suggest., that everything outside of the Assets-Folder should be ignored by default.

Indeed, since there is no filter on any folder here, all .uxml files are taken.

Rosalina/Editor/Scripts/RosalinaAssetProcessor.cs

Lines 14 to 16 in 50386ad

	string[] uiFilesChanged = importedAssets
	.Where(x => Path.GetExtension(x) == UIDocumentExtension)
	.ToArray();

This might happen when you re-import every assets in your project and thus, Unity's internal UIDocuments.
Thanks to your PR (#17) this might fix the issue. 😄
