feat: add Cloudflare Workers KV adapter

[KnorpelSenf]

I received a rudimentary JS file by someone without a GH account which implements a storage adapter for Cloudflare's key-value store called Workers KV.

This is an early draft. It contains the correct logic for all operations, but neither does it typecheck nor does it follow the right setup for a new adapter. Docs are missing, too.

Ideally, it'd be awesome if you could take over from here, @Satont. I can help with this, of course. Please let me know if you need anything.

Should we release it as npm package?

Definitely!

Definitely!

I just never worked with cloudflare workers, that's why asked.

[rojvv]

Same, but I thought it’s important to be an NPM package since the development is NPM-powered.

@KnorpelSenf should i mention you as author of npm package?

Also what name should we choose for that storage in npm? Something like @grammyjs/storage-cloudflare?

[rojvv]

@grammyjs/storage-cloudflare could be confusing since Cloudflare has other storage solutions. Maybe @grammyjs/storage-cloudflare-kv, @grammyjs/storage-cloudflare-workers, or @grammyjs/storage-cloudflare-workers-kv?

[rojvv]

I personally prefer @grammyjs/storage-cloudflare-workers-kv.

We do not know the name or username of the original author. Perhaps we use grammyjs?

Also what name should we choose for that storage in npm? Something like @grammyjs/storage-cloudflare?

I'll ask about this. The proprietary name is Workers KV, but I'm not sure if we maybe should include the name cloudflare, too. I'll get back to you.

@KnorpelSenf @roj1512 i think it's ready for review.
