get_bis() gets stuck trying to download LBS, CBS, SEC data sets

[stefanangrick]

Summary:
get_bis() gets stuck trying to download the "Locational banking statistics" (LBS), "Consolidated banking statistics" (CBS) and the "Debt securities statistics" (SEC) from the BIS's homepage.

Steps to reproduce:

library("BIS")
ds  <- get_datasets()

lbs <- get_bis(ds$url[grep("Locational banking statistics", ds$name)])
cbs <- get_bis(ds$url[grep("Consolidated banking statistics", ds$name)])
sec <- get_bis(ds$url[grep("Debt securities statistics", ds$name)])

Expected result:
The above calls to get_bis() should run through and assign the downloaded data to the objects before the "<-" operator.

What happened instead:
The download starts, showing a progress bar which gradually goes to 100%. After that, nothing happens for an extended period of time. After several minutes of inactivity, the system starts using up larger amounts of CPU resources and RAM, at which point I typically force-quit R/R-Studio.
