Breaking changes to allow custom generation options and multi-completions

[extremeheat]

BREAKING:

• CompletionService and GoogleAIStudioCompletionService
  • .requestCompletion now returns an array of completions

Non-brekaing:
.requestCompletion's options objects now also take in the following options:

    maxTokens: number
    temperature: number
    topP: number
    topK: number

Which will be passed to the model's generation options.

The constructors for CompletionService and GoogleAIStudioCompletionService have also been updated to take an additional objects object. These the object can contain a generationOptions dictionary that will be applied by default to all requestCompletion calls. You can override these options by passing them in individual requestCompletion calls.

Export a SafetyError object that can be used in instanceof checks to see if a model response failed due content filtering rules.
