v0.7.11-test5

Test build 5 - everything from test4 plus fixes to the viewer's GPU upscaling (U):

• RTX Video Super Resolution works on Windows (in test4 it did not start: "failed: input view"). Tested on an RTX 4060 laptop. It adds a few milliseconds of latency, so it stays off by default. Turn on RTX Video Enhancement -> Super resolution in the NVIDIA app too.
• U switches instantly on Windows between off, FSR 1, NIS and RTX VSR - no restart (the viewer changes between Direct3D 11 and OpenGL by itself).
• The full stats overlay (F3) says why a frame is not upscaled ("window too small" when the window is not bigger than the stream).

Still in this build from the earlier tests: screenshots next to the system's, a custom screenshot combo with the Capture button, the HOME menu fix, USB released while streaming is off, complete recordings, lower viewer latency, firmware 23.0 / Atmosphère 1.12, and the macOS and Linux viewers.

Firmware 23.0: streaming there is still untested - set allow_untested_firmware = 1 in config/switch-frame-tap/config.ini to try it, and please send config/switch-frame-tap/log.txt.

Installing: unzip switch-frame-tap-0.7.11-test5-switch.zip over the SD card root and reboot (settings are kept), and update the viewer. To go back, unzip v0.7.10 the same way. The macOS app needs macOS 12 or newer; it is not signed by Apple, so the first time right-click it and choose Open.
