Use case: On installing streamlink/streamlink-twitch-gui and streamlink/streamlink-appimage with pho, streamlink-twitch-gui wasn't able to easily find the streamlink binary, as it hadn't been added to the path. This feature would add an optional --link -l parameter to let the user set a symlink name that would be added to .local/bin or another configurable personal binary storage directory so the given AppImage is present in the path.

Current:

$ pho add github streamlink/streamlink-appimage
$ streamlink # not found

Expected:

$ pho add github -l streamlink streamlink/streamlink-appimage
$ streamlink # works
