Broken links in DownloardSRTMTiles
The DownloadSRTMTiles allows downloading SRTM tiles corresponding to the input images and vectors extent. But the download link used seems broken (as of 03/03/2021). It looks like accessing https://dds.cr.usgs.gov/ now requires login, something that is not possible with application.
The links on JPL SRTM page are broken. A similar bug has been reported on the readhgt Matlab module page
