Missing AQHI PM2.5 Sparwood Centennial Square 2022

`envair` version 0.4.0.300

Sparwood Centennial Square has PM2.5 data during 2022, but the AQHI PM2.5 is not in the AQHI dataset:

```
aqhi<-envair::importBC_data(parameter_or_station = "aqhi",
years = 2022,
use_openairformat = FALSE) %>%
dplyr::filter(STATION_NAME=="Sparwood Centennial Square")

#preview the data
head(aqhi %>%
dplyr::select(PARAMETER,
DATE_PST,
STATION_NAME,
contains("AQHI")))

pm25<-envair::importBC_data(parameter_or_station = "pm25",
years = 2022,
use_openairformat = FALSE) %>%
dplyr::filter(STATION_NAME=="Sparwood Centennial Square")

head(pm25 %>%
dplyr::select(PARAMETER,
DATE_PST,
STATION_NAME,
RAW_VALUE))
```


Reproduce the two importBC_data calls for AQHI and PM2.5 for Sparwood Centennial Square in 2022, then trace the importBC_data entry point and the data source handling those parameters. Done means the AQHI dataset contains the station's 2022 PM2.5 records consistently with the PM2.5 dataset.
