docs: Compile a set of source break rules into the binary state tables used
  by the break iterator engine.  Creating a break iterator from precompiled
  rules is much faster than creating one from source rules.
  
  Binary break rules are not guaranteed to be compatible between different
  versions of ICU.
  
  
  @param rules  The source form of the break rules
  @param ruleBinary  An output stream to receive the compiled rules.
  @throws IOException If there is an error writing the output.
