The HiLink s/w now require the sessionID to be passed with each api request. This is the issue reported in #3

The following PR works on:

Huawei E3372 LTE Modem
Hardware version: CL2E3372HM
Software version: 22.315.01.00.74
Web UI version: 17.100.14.00.74

Signal strength reporting has also changed and this is not working. Further investigation needed.

Code changes based on:

With regards to "Signal Strength", this is no-longer retured from "/api/monitoring/status":

$ curl -s -X GET http://192.168.8.1/api/monitoring/status -H "Cookie: SessionID=kfTrKwuV3KbAvBPIojFeJDPd2NqDOm4DnHtzEEEPTEV/eVolHKq34qI14PBC5oP34nJnsYF71tbytW3rugElShk3l47fBLZdRiWat2OiIi8j3UJAAo7ady82iDfuVKgG"

Possibly modify to use "api/device/signal" which gives more detailed signal information:

$ curl -s -X GET http://192.168.8.1/api/device/signal -H "Cookie: SessionID=SYoUHwtYXKQPJDtnT47WmvfV03qbGJJljWSgheV47+JRRX1RXu6YgOXkDnU60ClDt0h2AqV602afVecLOePbAfd3ik/fhIBaWfDq16zLv8kJsyq7vL/IXL+OW5Q7fHVl"
