Breaking change request: Drop js-logger dependency

[simolus3]

We currently use the js-logger package in all of our JavaScript SDKs. This package is not particularly popular and uses weird TypeScript definitions giving us pain when we try to bundle it.

So, we'd like to migrate away from that package, towards something more usable in modern JavaScript. Most likely, we would define our own simple logging interface and let users implement that. The interface might look like this:

type LogLevel = 'trace' | 'debug' | 'info' | 'warn' | 'error';

interface PowerSyncLogger {
  log(tag: string, level: LogLevel, ...message: any[]): void;
}

We would continue to export a trivial createDefaultLogger(minLevel?: LogLevel) implementation forwarding logs to console.log. The main benefits is that this reduces our dependency footprint, removes logger features we don't need and makes it easier to integrate custom logging packages for apps that might already depend on those.

This is a breaking change for users providing their own loggers, so feedback and ideas are definitely welcome!
