Add generating style concise, normal, formal, explanatory

[SNNafi]

First of all thanks for this package. Claude has introduced concise, normal, formal, explanatory writing styles.

Can you please add them in the script?

This way we can use the chat more using concise style when necessary.

Thanks for reaching out, I don't know when I will have the time to work on this feature.

But if you'd like, feel free to open a pull request, in case you already figured it out.

@SNNafi I created a PR with the new changes for 0.3.4

Although everything works normally, I wasn't able to verify if the styles are applied correctly.

Would need some help verifying it before merging, thanks in advance.
