Test build T180-load-fixes (for testers)

A test build for people who already help test and know the setup. Not a release. New here? Please wait for the alpha.

• Install: as under "For testers" on the front page. Replace the whole PPSA98515 folder. No game, keys or firmware are included.
• Settings: the env.txt in the zip is play settings v3.9 (the same file as envs/Vampinity/play-v39.env.txt). Set handheld at 1x in the app's menu, because that is how it was tested. On firmware 13.x, change EDEN_GUEST_SWAP_AHEAD_MIB=12288 to 2048.
• What it is for: the load from the field into the next area. In scripted starts with these settings, 3 of 3 got through on T180, and later 2 of 3 on T181 and 1 of 2 on T184. The starts that got through still froze for 3 to 9 s at that load. Scripted starts only, not played by hand yet.
• Known problems: the area after the field runs at about 15 fps. Starts with these settings also still sometimes die at that load; a change aimed at that is in T181, not in this build. If you are coming from T120, the first start builds the shader store again, so expect freezes the first time you see things. The whole-game shader step is not switched on in these settings.

Changelog: 13 November in CHANGELOG.md. Source: source/T180.

Edit 14 Nov: corrected the load counts (v3.9 per build: 3 of 3 on T180, 2 of 3 on T181, 1 of 2 on T184; not 7 of 7).
