feat: Add modern JetCoDatePicker component

[kadubhumika]

Description:

Hey 👋 I’d love to contribute a modern DatePicker component to JetCo!

Why this feature

JetCo’s README mentions that “Date Pickers” are coming soon .

Compose’s default picker is quite plain — this one can match JetCo’s modern, customizable UI style

It’ll be useful for developers building forms, event apps, or calendar-based UIs

Planned Features

1. Modern, rounded DatePicker UI

2.Theme color customization (primary, secondary)

3.Dark/Light mode support

4. Month swipe animation

5.Optional date range selection

Hey @kadubhumika 👋

Yes, you can definitely create a Modern DatePicker component for JetCo — we’d love to see your contribution!

Here are a few guidelines to help maintain consistency with the library standards:

• Ensure the code is clean and follows Jetpack Compose best practices.
• Keep the component highly customizable — that’s what makes JetCo special.
• Use a data class for parameter grouping (e.g., DatePickerConfig, DatePickerAnimationConfig, etc.).
• Prefer Compose in-built libraries. If you use any external libraries, please document their purpose and requirements.
• Add proper KDocs for clear documentation.

It might seem like a detailed process, but it really helps us keep the library polished and developer-friendly.

If you need any support, feel free to reach out to me about this. 🙌
