feat: Add Rabin–Karp string search algorithm in R

[sgindeed]

• Implemented the Rabin–Karp string search algorithm in R.
• Finds all occurrences of a pattern in a given text using rolling hash.
• Efficient for multiple pattern searches in large texts.
• Handles case-insensitive input.
• Prints the starting positions of all matches.
• Time Complexity: O(n + m) average, O(n*m) worst case.
• Space Complexity: O(1)
