Shuffle Algorithms for Various Scenarios
This PR introduces multiple shuffle algorithms to the com.thealgorithms.shufflealgorithm package, with each class implementing a specific type of shuffle technique. The classes are designed to be flexible for different shuffling scenarios with well-documented methods and edge case handling. Below is a summary of the classes and the shuffle techniques they provide:

1. ConstrainedShuffle
   Purpose: Shuffle the elements in an array while keeping the first and last elements fixed.
   Method: constrainedShuffle(int[] array)
   Edge Case Handling: No shuffling occurs if the array has fewer than 3 elements.
2. GroupShuffle
   Purpose: Groups elements into subarrays of a specified size and shuffles those groups.
   Method: groupShuffle(int[] array, int groupSize) -> List<List>
   Edge Case Handling: Ensures that each group has the specified size (or fewer for the last group) and skips shuffling if groupSize <= 1.
3. ShuffleByRange
   Purpose: Shuffle elements within a specified index range.
   Method: shuffleByRange(int[] array, int start, int end)
   Edge Case Handling: Verifies valid indices to avoid IndexOutOfBounds issues.
4. UnderstandingShuffleAlgo
   Purpose: Basic shuffle algorithm that uses a uniform probability approach to randomize array elements.
   Method: shuffle(int[] array)
5. UniquePairShuffle
   Purpose: Pairs elements randomly without repeating pairs.
   Method: pairShuffle(int[] array) -> List<int[]>
   Edge Case Handling: Returns an empty list if the array has an odd length or fewer than 2 elements.
6. WeightedShuffle
   Purpose: Shuffles elements based on their weights, favoring elements with higher weights.
   Method: weightedShuffle(int[] array, int[] weights)
   Edge Case Handling: Ensures the weights array matches the array length for proper assignment
