D303: model converter copied 1/4 of each star muzzle flash's vertices

The op-22 DisplayListPrimaryRecord count is the number of star-flash
arms; dorottex (and PD's modelRenderNodeStarGunfire) read count*4
vertices. d43_emit/d43_convert sized the array as count vertices, so
3/4 of every muzzle star came from neighbouring sidecar bytes and drew
as long spikes (M16 "shooting up"). Size it 16*4*count. Emitter
round-trip checks all pass; M16 renders a clean star headless.

Also TEMP GE_STARTWEAPON (bondview_r.c) for weapon repros. Re-run
tools_pc/d43_emit.py to regenerate data/pcmodels-*.
