title: Writing unsigned types to a Netty ChannelBuffer
body: <p>Netty's ChannelBuffer class provides convenient methods for reading unsigned types from a ChannelBuffer, however there don't appear to be any equivalent methods for writing unsigned types to a ChannelBuffer.</p>
  
  <p>I feel like I must be missing something.  What's the recommended approach for say, writing an unsigned integer to a ChannelBuffer?</p>
  
  <p>Thanks!</p>
