Adds a profile and note for Return of the Obra Dinn (010032E00E6E2000), with its row in dm/games/README.md and a gallery entry.

• Unity 2017.4.28f1 IL2CPP, NVN, SDK 8.2.1; modules main, subsdk0 (movie), sdk
• 1,260 shaders; the game has no PC version to pair against, so shader_pairs.tsv holds one pair
• tested on the Mac: the save-slot menu, the opening letter and the ship's deck at 60 fps with audio, no crash and no dropped frames
• two pipelines fail to build at startup (user(locn1) mismatch) and their draws are skipped; noted as open in the profile
• not tested on iPhone, and there is no smoke.tsv route

This is a first contribution and mostly a way to get the hang of the toolchain, so the note is a starting point rather than the finished article.

A separate commit carries the two small changes this game needed to build: a jump-table form in dm/tools/patch_nso.py and the Unity 2017.4 Shader type tree in dm/gfx/tools/unityfs.py. Happy to split them out or leave them for you to take differently.

Closes #426

Closing this as superseded. While it was open, upstream landed its own profile for this game (06ce3ce7, 1.0.1), the jump-table recognition fix (e34fe271), the Unity 2017.4 Shader and ComputeShader type trees, and a generated README gallery (#401). Nothing here is needed on top of that. It was a good first run through the toolchain — thanks.
