    Usage example

    const { IOBuffer } = require('iobuffer');
    
    const io = new IOBuffer();
    // Pointer offset is 0
    io.writeChars('Hello world') // Write 11 chars, pointer offset now 11
      .writeUint32(42) // Write 32-bit int (default is little-endian), pointer offset now 15
      .setBigEndian() // Switch to big-endian mode
      .writeUint32(24) // Write another 32-bit int, but big-endian, pointer offset now 19
      .mark() // Bookmark current pointer offset (19)
      .skip(2) // Pointer offset now 21
      .writeBoolean(true) // Write 0xff, pointer offset now 22
      .reset() // Go to bookmarked pointer offset, pointer offset now 19
      .setLittleEndian() // Go back to little endian mode
      .writeUint16(18) // Write 16-bit unsigned integer in the previously skipped 2 bytes, pointer offset now 21
      .rewind() // Pointer offset back to 0
      .toArray(); // Get a Uint8Array over the written part [0-21] of the internal ArrayBuffer
