Typos in os_all.json

[CFTBL]

At first I opened this issue under procount/pinn, but it probably belongs here, under procount/pinn-os...

I think there are a couple of typos in procount/pinn-os/tree/master/os/os_all.json that prevent lineage17-rpi4 OS's from installing. Specifically...

The OS "lineage17-rpi4-atv" won't install because, in the json file...

"http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4-atv/system.tar.xz" SHOULD BE "http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4-atv/system.img.xz"

and

"http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4-atv/vendor.tar.xz" SHOULD BE "http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4-atv/vendor.img.xz"

ALSO...

The OS "lineage17-rpi4" won't install because, in the json file...

"http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4/system.tar.xz" SHOULD BE "http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4/system.img.xz"

and

"http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4/vendor.tar.xz" SHOULD BE "http://downloads.sourceforge.net/project/pinn/os/lineage17-rpi4/vendor.img.xz"

I could be wrong, but I think that's why I'm seeing an "Error 404: Not Found" error when trying to install those particular OS's.
