  /**
   * Provides Base32 encoding and decoding in a streaming fashion (unlimited size). When encoding the default lineLength
   * is 76 characters and the default lineEnding is CRLF, but these can be overridden by using the appropriate
   * constructor.
   * <p>
   * The default behaviour of the Base32OutputStream is to ENCODE, whereas the default behaviour of the Base32InputStream
   * is to DECODE. But this behaviour can be overridden by using a different constructor.

   * Since this class operates directly on byte streams, and not character streams, it is hard-coded to only encode/decode
   * character encodings which are compatible with the lower 127 ASCII chart (ISO-8859-1, Windows-1252, UTF-8, etc).
