Weather station support

[TristanBrotherton]

Hello, I saw a few people wanting to add multiple temp sensors for weather stations, but this wasn't possible. So I added the support for a weather station qxj - An example config might be like:

"schema": [
                            {
                                "code": "ToutCh1",
                                "newCode": "va_temperature"
                            },
                            {
                                "code": "HoutCh1",
                                "newCode": "humidity_value"
                            },
                            {
                                "code": "ToutCh2",
                                "newCode": "va_temperature"
                            },
                            {
                                "code": "HoutCh2",
                                "newCode": "humidity_value"
                            },
                            {
                                "code": "ToutCh3",
                                "newCode": "va_temperature"
                            },
                            {
                                "code": "HoutCh3",
                                "newCode": "humidity_value"
                            }
                        ]
