/**
 * Put accessories on a rigged 3D model for Directional Sprites: up to 8 items, each at the `placement` fitDirectionalAccessory returned (or, without one, at the automatic fit plus the same size/move/turn adjustments). Returns `model_url`, one GLB of the model holding them all (kept 7 days): pass it as `model` to createDirectionalSprites, createDirectionalStills or previewDirectionalSprites. When `model` is the URL of one of your 3D models (as listGenerations or create3DModel returned it), the items are also saved on that model (`saved: true`; `save_on_model: false` skips it), so the Ludo web app's Directional Sprites shows them on it. Items the model already had saved stay on it and in the GLB (`kept`), except those held by a bone a new item takes; `keep_saved: false` replaces them all. Free (no credits) and synchronous. Requires an API key (user scope).
 * 
 * POST /assets/sprite/directional-accessories
