Add test suite for similarity.go

Description:

Create a comprehensive test suite for the similarity.go file to ensure the correctness of image comparison and grouping functions.

Tasks:

• Create a new file similarity_test.go in the root directory
• Implement test cases for the following functions:
  • findSimilarImages
  • groupByFileHash
  • groupByImageSimilarity
  • getRemainingImages

Test:

• Test findSimilarImages:

  • Test with a set of identical images (same file hash)
  • Test with a set of visually similar images (different file hash)
  • Test with a mixed set of identical, similar, and unique images

• Test groupByFileHash:

  • Test with multiple images having the same file hash
  • Test with all images having unique file hashes

• Test groupByImageSimilarity:

  • Test with visually similar images
  • Test with visually distinct images
  • Test performance with a large number of images

• Test getRemainingImages:

  • Test with some images already grouped
  • Test with all images grouped
  • Test with no images grouped

Additional Tasks:

• Update README.md to include information about running the new test suite
• Ensure proper error handling and edge cases are covered in the tests
