Setup the observer so it know how to notify the answer

Feed a block of bytes to the detector.

It will call the Notify function of the nsICharsetObserver if it find out

aBytesArray - array of bytes
67
aLen - length of aBytesArray

oDontFeedMe - return PR_TRUE if the detector do not need the following block

This is used to enhance performance
