Reads a boolean from the reader object's stream and returns that boolean value.

ReadBoolean is a helper method used by other reader methods to read a tagged boolean value at the current reader Position. ReadBoolean uses ReadValue to check the type for a vaTrue value and returns that result. Note that ReadBoolean will not verify that the value being read is a boolean, only whether or not the value is true.
