[POF] lodown download issue

[gpompeo]

I am getting a download error when I try to get the POF catalog. Here are the messages I get:

I have the 7-zip installed.

UPDATE: I tried changing filesize_fun to fix download from FTP considering that httr is not supposed to work with ftp (r-lib/httr#537). Got the download going but got stuck in a loop downloading (and unzipping) the file until ran out of attempts.

Hey @gpompeo, I managed to fix the problem with the httr:HEAD changing the filesize_fun parameter as well and updated the link from 2017-2018 that was broken. Made a pull request for that. Despite that, after downloading and unziping the files, my script stops to work at the step of unpacking the 7z files. It actually unpacks one file but something happens after that.

Have you find the solutions to make the package work properly?

@gocdata I haven´t managed to get it to work properly. I´ve noticed that there were several changes in the POF (specially on the first releases) so I tried a different path and managed to pre-process the files manually.
