download_vpfiles() currently broken

[peterdesmet]

https://lw-enram.s3-eu-west-1.amazonaws.com no longer exists, so the function download_vpfiles() is currently broken:

library(bioRad)
#> Welcome to bioRad version 0.7.3
#> using vol2birdR version 0.2.2.9043 (MistNet not installed)
download_vpfiles(radars = "bejab", date_min = "2023-10-10", date_max = "2023-10-11")
#> Downloading data from https://lw-enram.s3-eu-west-1.amazonaws.com
#> bejab202310.zip: http error 404

^{Created on 2023-12-14 with reprex v2.0.2}

The function should be updated to read from the aloftdata bucket. See also #553 where it is suggested to rename the function to download_vpts_aloft() (with support for hdf5). I'm more in favour of having a generic download_files() function, which can be fed with a vector of URLs. That vector can be created with list_vpts_aloft().

Note that for that later route #647 also needs to be resolved
