S3 clients list

[psam44]

On /addons/cellar:

1. The right link is https://www.filestash.app/
2. I suggest to add WinSCP (https://winscp.net).
   As a personal point of view, I would like it to be mentioned at the top of the list (as a recommended choice). Just because I use it since decades to browse and upload the file system of remote servers.
   I discovered its S3 file protocol capability by the luck of a search, just to have a glance about S3 clients, and so it saved me the installation of one more software.
