PPS counter and INST counter are very different #112

In this line, converting CNT to UTC is calculated by local_ref, local_ref and time_reference_gps equal. But ref is derived from PPS counter, and the values of PPS counter and INST COUNTER are already well over 1s。

SX1302 counter (INST): 4208287192 SX1302 counter (PPS): 718559044

So the 'time' calculated in JSON Up is wrong

JSON up: {"rxpk":[{"jver":1,"tmst":4210558634,"time":"2023-08-16T10:37:34.999590Z","tmms":1376217472999,"chan":0,"rfch":0,"freq":903.900000,"mid": 8,"stat":1,"modu":"LORA","datr":"SF10BW125","codr":"4/5","rssis":-105,"lsnr":8.5,"foff":-196,"rssi":-105,"size":22,"data":"QKQIAEiAZ3QCz+548az544fTLvtZCA=="}]}

question: Is this PPS counter abnormality a problem with the SX1302 chip?
