\`Make or change my application's decision on a Travel Rule counterparty VASP.

Endpoint:
PUT https://verification.didit.me/v3/travel-rule/vasps/{vasp_id}/decision/

Authentication:
Use the x-api-key header with my Didit API key.

vasp_id is the id GET /v3/travel-rule/vasps/ returns for a directory entry or a Didit network member.

Example call:
curl -X PUT "https://verification.didit.me/v3/travel-rule/vasps/{vasp_id}/decision/" \
-H "x-api-key: YOUR_API_KEY" -H "Content-Type: application/json" \
-d '{"decision": "BLOCKED", "reason": "Unlicensed in its home jurisdiction"}'

Body:
\- decision (required) - APPROVED, RESTRICTED or BLOCKED.
\- reason (optional) - up to 255 characters. It replaces the previous reason; leaving it out clears it.

The response is {"decision": {decision, reason, decided_by, updated_at, inherited_from}} as it now applies.

How it works:
\- The decision is private to my application: no other Didit customer sees it, and it never changes the shared directory entry or how a transfer is routed.
\- A decision on a brand also covers each of its entities that has no decision of its own (inherited_from names the brand there). A decision on an entity overrides the brand's for that entity.
\- It acts only through my transaction rules, through the rule field counterparty_dd_status. Install the presets travel-rule-counterparty-blocked (declines) and travel-rule-counterparty-restricted (holds for review), or write my own rule on that field.

Failure modes:
\- 400 - decision missing or not APPROVED, RESTRICTED or BLOCKED, or reason longer than 255 characters.
\- 404 - no directory entry or listed Didit network member has this id, or the id is my own VASP profile.
