Arguments

sites	a character vector of valid NWIS site IDs
var	short name of var as in unique(get_var_src_codes(out='var'))
src	short name of the NASA-LDAS source, either 'nldas' or 'gldas'
times	a length 2 vector of POSIXct dates, or characters convertable to POSIXct dates
url	for web dataset. Required because there are corrections for certain urls
folder	a folder to place the file outputs in (defaults to temp directory)
version	character string indicating whether you want to stage the ts as a .tsv or .rds
