BinTreeNodeReader::peekInt8($offset=0): parameter $offset is unused

[zjorzzzey]

the method BinTreeNodeReader::peekInt8($offset=0) always returns the int8-value at offset 0. This doesn't seem to affect the functioning of WhatsAPI as of yet, but it would be nice to have this fixed before someone unknowingly starts using it (for reference, see peekInt16 and peekInt24, these are correct).

expected result:

$sbstr = substr($this->_input, $offset, 1);    // returns the 8-bit value from offset $offset

current code:

 $sbstr = substr($this->_input, 0, 1);    // returns the first 8-bit value in the input buffer
