Remove getRawData() and getDataLength()

Browse source 
Previously getRawData() made an unnecessary copy of the remote characteristic value data in order to return a uint8_t*. The resources used for this was unjustified by the value it provided as templates to retrieve such data have been added. Also the application writer could cast the std::string result of readValue() and/or getValue() however they choose using the data() method on the container if desired.

getDataLength() is also an unnecessary function as the length can be retrieved by the returned std::string from readValue() and/or getValue() with the length() method.
