Create random_sample function

[luminousmen]

We need to develop a random data sampling function that can generate representative data samples from Avro/Parquet/CSV/JSON files.

AC:

• Create a data sampling function that accepts input files in Avro/Parquet/CSV/JSON formats. Interface:

  def random_sample(file_path: Path, n: Int, output_path: Path):
   ...

• Allow the function to specify the number of random records to sample from the input file.
• Ensure that the sampled data maintains the structure and schema of the original file.
• Implement a mechanism to randomize the selection of records, ensuring a truly representative sample.
• Provide an option to output the sampled data to a new file.
• It should support existing data sample files from the tests/data directory
• Write unit and integration tests to validate the correctness of the sampling function.
• Integrate the function into the interface
• Ensure the function is easy to use with a clear and well-documented API.
