0.1.4

I would have tagged this significant release with lots of breaking changes, but thanks to God, we still don't have a stable release.

In this release, I reworked the hosted providers to generate the checkout URL from the gateway providers.

Completed the implementation for the following providers:

• Paystack 🔥
• Flutterwave 🔥
• Stripe 🔥

That's all for now, more implementation is coming for Monnify and Paypal 🚀
