Usage: mv_data [OPTION...]
Move data from an input file to an output file.

Reads a specified number of bytes from the input file at a given offset and
writes them to the output file at a specified offset. After writing each chunk
of data, the storage space in the input file is immediately freed using
fallocate with FALLOC_FL_PUNCH_HOLE. This allows for moving large sections of
data without requiring significant storage overhead.

      --input=FILE           input file name (required)
      --input-offset=OFFSET  input offset in bytes (default: 0)
      --output=FILE          output file name (required)
      --output-offset=OFFSET output offset in bytes (default: 0)
      --length=LENGTH        length in bytes (default: input file size)
