cbor_encode_half_float() get error value

[tianxiaoMCU]

Tested in QT 5.12

    float halfdata = 23.5;
    uint8_t buf[16] = {0};
    CborEncoder encoder;
    cbor_encoder_init(&encoder, &buf, sizeof(buf), 0);
    cbor_encode_half_float(&encoder, &halfdata);

run the demo,the encode data is F9 00 00

You've passed the pointer to a (full) float to cbor_encode_half_float. You're supposed to pass a pointer to a half float data, by using qfloat16, __fp16 or cbor_encode_float_as_half_float (see PR #149 for this function) or some other function of yours.
