Create a new post.

Specifying the post author (explicit-user rollout): When the explicit-user
rollout is enabled for the organisation, data.userUuid is an optional author
override. Campaign API key authentication (Authorization header, Bearer
raisely-sk-...) and organisation/campaign admins may supply data.userUuid to
author the post on behalf of any user in the same organisation; a userUuid from
another organisation returns 404 not found. data.userUuid is never required —
when it is omitted (or supplied by a non-admin who cannot override), the author
defaults to the authenticated user. Non-admin callers cannot author as someone
else.

For custom components:

RaiselyComponents.api.all('posts').post(data = {}, params = {}, headers = {}) => Promise<{result}>
