Add Subscriptions

[ramitbuilds]

Right now we are using our own API key which costs us so we can do 2 things:

1. BYOK (Bring your own API key)
2. Subscription

After we keep BYOK (i have opened issue at #106 ), some users will use their own api key, but some won't use their own and will depend on our api keys so we can add a subscription too (credits-based) so if they dont want to use their own api key, they can directly use free credits or buy subscription.

@ramitbuilds explain your idea a bit clearly about this issue here or in #106 like how u gonna implement this!!

[ramitbuilds]

@abhro05 we can do like as we will be inplementing a feature in which users will have to use their own api key to use the website, we can also add subscription with dodo payments so instead of bringing their own api key, users can buy our subscription or use free tier to use the program.
