- added more es commands. - fixed usb install potential hang if the exit command is sent, but the client stops responding (timeout is now 3s). - added multi select to the games menu. - added game dumping. - added switch2switch support by having a switch act as a usb client to transfer games. - replace std::find with std::ranges (in a few places). - fix rounding of icon in progress box being too round. - fix file copy helper in progress box not updating the progress bar.
