Caller: [name: string, version?: string]

The caller information to send with requests, of the form [name, version?], or an array of such.

Intended generally for integrations or frameworks that wrap the client.

Used to identify the client making requests to the server.

It will be sent in the headers of the request as such:

User-Agent: ...<name>/<version> astra-db-ts/<version>

If no caller information is provided, the client will simply be identified as astra-db-ts/<version>.

NB. If providing an array of callers, they should be ordered from most important to least important.
