ot::Spinel::Decoder::ReadDataWithLen() method

Decodes and reads a data blob (sequence of bytes) with data length. The data length is assumed to be prepended before the data content (encoded as a `uint16_t`). The size of the length field should not be included in the length value. This method corresponds to `SPINEL_DATATYPE_DATA_WLEN` type.
