Company features

GET https://app.pennylane.com/api/external/v2/company/features

Effective availability of the features that are gated for this company,
so that they can be checked before calling the endpoints they restrict.
A feature is true only when every gate is open, including the billing plan
and the progressive rollout, so it can be false on a plan that includes it.
Keys are added here as new gated features are introduced.
