Suggest to rename argument in senSearch #10

I noticed when trying to retrieve URLs from senSearch that the argument name "lonlat" and its description is misleading. I was searching for the point 97.65317 (lon), 24.15859 (lat), so in the "lonlat" argument I put it in this order. However, the function returned NULL saying there were no images, even though a manual search in Copernicus SciHub showed there was.

I tried switching the argument to lat, then lon, and the function worked.

Can I please suggest you rename the argument to be "latlon" and update the description?

Here is the code. First one does not work.

senSearch(
            username="****",
            password="*****", 
            verbose=TRUE, 
            platform="Sentinel-2", 
            product="S2MSI1C", 
            lonlat=c(97.65317, 24.15859), # c(lon, lat)
            startDate=as.Date("2015-01-01"), 
            endDate=as.Date("2018-12-17")
)

This one works.
