Upstash Redis LevelDB Implementation

upstash-redis-level is an `abstract-level` database implementation that utilizes @upstash/redis as its underlying data store. The `abstract-level` interface provides a common API for lexicographically sorted key-value databases, featuring support for encodings, sublevels, events, and hooks, enabling developers to swap out storage backends easily. This package, currently at version 1.1.1, integrates with Upstash's serverless, low-latency, HTTP/REST-based Redis offering, making it particularly well-suited for edge and serverless environments like Vercel, Cloudflare Workers, and Next.js where traditional TCP-based Redis connections are often suboptimal or unavailable. It differentiates itself by leveraging the connectionless nature of @upstash/redis to avoid common issues like connection limits in ephemeral environments.
