vangel76andClaude Opus 5.5 fe52bc0b2c #821: import Targa and DPX stills and image sequences
Problem: Premiere imports Targa and DPX as stills and numbered sequences.
FilmCraft exports both (#779) but could not read either: the extensions
were not importable and the image crate has no DPX reader, so even our
own Targa / DPX renders could not come back in.

Fix: clean-room decoders in filmcraft-media. Targa from the TGA 2.0 spec:
image types 1/2/3 and RLE 9/10/11, colour maps, 15/16/24/32-bit, 8/16-bit
grayscale, any origin. DPX from SMPTE ST 268: first element, luma / RGB /
RGBA / ABGR, 8/16-bit, filled 10/12-bit (methods A and B), either byte
order, padded lines, orientations 0-3. Both bound allocations by the
data present and reject hostile headers with errors. Stills and image
sequences share one decode_raster entry point; "tga" and "dpx" join the
importable still extensions.
