Add support of presence_penalty and frequency_penalty parameter

[PeterDaveHello]

The frequency and presence penalties help reduce the likelihood of repetitive token sequences, allowing for more varied and contextually appropriate outputs.

By implementing these options, we can gain finer control over the AI's behavior, leading to improved content generation.

@josStorer please let me know what do you think ;)

Different APIs have varying default values for presence/frequency penalty. Typically, the default values used by APIs are sufficient for common application scenarios. Setting a global default value for these two parameters might be helpful for specific user scenarios, but it could also negatively impact the performance of certain APIs.

Of course, there's nothing wrong with this PR itself. The default values for these two parameters in the OpenAI API are both 0, but this could affect users who utilize custom APIs. In contrast, the temperature parameter is more commonly used, its impact is more predictable, and it is sufficient for most users, which can also reduce the complexity of the software itself.

I believe that the target users of ChatGPTBox will hardly ever need to modify these two parameters.

If we do decide to provide this feature, it would be best to add a CheckBox component to make it optional, or even better, allow each API to configure these parameters individually. However, due to my personal laziness, and considering the increase in software complexity, along with the fact that I don't think this feature is very important, I have been procrastinating on implementing it. 🤣

You're right, I can see how to add a CheckBox component for them. Hopefully, with some help from AI assistants, it won’t take much time. 😆
