Gracefully throw exception instead of using fatalError

[Daniel Nguyen]

Hi. I think as a library, SSK should gracefully throw an exception and let the application handle it instead of crashing the app.

What do you think? @ZachNagengast

similarity-search-kit/Sources/SimilaritySearchKit/Core/Index/SimilarityIndex.swift

Line 119 in d591adc

 fatalError("Failed to generate a test input vector.") 

[Zach Nagengast]

Yes very much agreed.

It would be great to know why this is failing if you have any more debug info.

similarity-search-kit/Sources/SimilaritySearchKit/Core/Index/SimilarityIndex.swift

Lines 115 to 121 in d591adc

 private func setupDimension() async { 
     if let testVector = await indexModel.encode(sentence: "Test sentence") { 
         dimension = testVector.count 
     } else { 
         fatalError("Failed to generate a test input vector.") 
     } 
 } 

In the meantime, this can definitely fail more quietly.

@longseespace this should be addressed in release 0.0.9 https://github.com/ZachNagengast/similarity-search-kit/releases/tag/0.0.9 but definitely lmk if you get anymore info about why the setupDimension is failing sometimes.
