Add an in-explorer video player for the dat/movie/*.wmv cutscenes.
Decode via the ffmpeg/ffprobe CLI (no libav linking): video streams from an
`ffmpeg -f rawvideo -pix_fmt rgba` pipe read into fixed w*h*4 frame chunks over
a bounded channel (paused/behind => ffmpeg back-pressures on its pipe); one
reused Image is overwritten in place each tick. Audio is best-effort: the track
is pre-decoded to a temp stereo WAV and played through a rodio Sink (volume /
play / pause / seek-via-skip_duration for free). Native-only under
cfg(not(wasm32)); VideoPreview registers unconditionally so the UI compiles for
wasm. Mirrors the .pak load pipeline (FileSelected -> bg thread ->
IsoLoaderMsg::VideoLoaded -> apply_loaded_video -> advance_video_playback), with
a single free_video teardown wired into every other viewer's reset.
Controls:
- play/pause button, click-on-frame toggle, Space / arrow (+-10s) shortcuts
- seekable timeline with mm:ss labels; volume slider (greyed when no audio)
- live scrubbing: a coalescing one-shot `ffmpeg -ss -frames:v 1` grabber always
jumps to the knob's latest position, so dragging shows the frame under the
knob in real time; that grabbed frame also bridges the gap after a commit-seek
so there's no black flash while the streaming decoder catches up.

Reworks the XPR2 texture path after RE against the retail disc (viewer
previews were scrambled/failed).
- de-tile: replace the naive Morton-over-32×32 approximation with the
faithful Xenos Tiled2D bank/pipe/macro-tile address formula (ported
from xenia texture_address.h). Verified correct: the Acheron backdrop
decodes to a sharp planet with its spiral storm.
- endian: undo the X360 word byte-swap per the fetch-constant endianness
field (k8in16/k8in32/k16in32) — without it BCn/ARGB data is noise.
- cubemaps: parse TXCM resources (skybox/backdrops), decoding face 0,
instead of erroring "No TX2D found".
- A8R8G8B8: correct channel order after the k8in32 swap ([A,R,G,B]→RGBA)
— the Acheron backdrop is now correctly green, not red.
- XPR files are texture PACKS; add XPR_RES_INDEX to select a resource.
- CLI `texture export` now writes real PNGs (texpresso BCn decode +
image), replacing the stub. Adds texpresso + image deps.
- tests/texture_disc.rs: integration test running the pipeline over real
disc .xpr files (28/28 parse). RE debug knobs: XPR_NO_DETILE /
XPR_NO_ENDIAN / XPR_FORCE_ENDIAN.
KNOWN ISSUE: mipmapped DXT1 textures still decode to noise — mip 0 is
not at base_address in the multi-resource packs (localized to a mip
storage-offset quirk; uncompressed + de-tile + endian are all verified).
