Download the pinned Streamline runtime for DLSS Frame Generation, and let the build kit carry it too.

Browse Source 
make_launcher.py --dlssg needed --streamline, a Streamline SDK folder unpacked by hand, and make_kit.py could not
carry DLSS Frame Generation at all, so a game built from the kit always left it off. tools/streamline_pin.py now pins
the Streamline 2.14.16 SDK release (its archive's size and SHA-256, and the SHA-256 of each file the game loads):
without --streamline the scripts download the archive once, check it, keep only sl.interposer.dll, sl.common.dll,
sl.dlss_g.dll, sl.pcl.dll, sl.reflex.dll, nvngx_dlssg.dll and the two licence texts, each checked, and delete the
archive. A folder given with --streamline must hold the pinned files.

The bin/dlssg/ assembly moves from make_launcher.py into streamline_pin.place, so the release and the kit write the
same set and the same dlssg-NOTICE.txt: a kit made with --dlssg and the 0.6.0 release's nx2navi_dlssg.dll has a
bin/dlssg/ identical to the 0.6.0 release's, byte for byte. make_kit.py takes --dlssg [--streamline] like the
launcher. nx2navi_dlssg.dll itself still comes from tools/build_dlssg.py.

tests/launcher_test.py test_streamline_pin covers the extraction, the cache, refused archives and folders, and the
notice.

- The build copies NVIDIA's DLSS library `nvngx_dlss.dll` (with `nvngx_dlss-NOTICE.txt`, which names its licence)
and FSR 3.1's `amd_fidelityfx_vk.dll` beside `ocarina.exe` from the kit's `bin\`. To use another DLSS version, put
your own `nvngx_dlss.dll` there: later builds keep it.
- A kit with `bin\dlssg\` (made with `tools/make_kit.py --dlssg`) also brings DLSS Frame Generation on GeForce RTX 40
and 50 cards: the build copies `nx2navi_dlssg.dll`, NVIDIA Streamline's runtime, `nvngx_dlssg.dll` and their licence
texts beside `ocarina.exe`, and Frame generation in the Screen menu then offers DLSS too.
- Logs are in `logs\`. When reporting a problem, say where you were in the game and which graphics card you have, and
attach `logs\nx2navi.log`. Never send game files.
