Allow specifying parameters in the RealtimeApi constructor

[thekid]

Parameters can now (also) be passed as a map instead of having to supply them all inside the URI string, which becomes hard to read when lengthy.

use com\openai\realtime\RealtimeApi;
use util\cmd\Console;

$api= new RealtimeApi('wss://example.openai.azure.com/openai/realtime', [
  'api-version' => '2024-10-01-preview',
  'deployment'  => 'gpt-4o-realtime-preview',
]);
$session= $api->connect(['api-key' => getenv('AZUREAI_API_KEY')]);
