feat: add onHotReloadLog

[felangel]

Description

As a developer, I want to be able to access any/all logs from the hotreloader so that I can fully customize the user facing logging experience. One use case is surfacing hotReload errors to users which is currently not possible.

This pull request adds an optional onHotReloadLog and a logLevel parameter which enable developers to configure the log level and intercept/handle any logs from the underlying hotreloader.

Example Usage

final myLogger = Logger();

withHotreload(
  () => createServer(),
  onReloaded: () => myLogger.log('Reload!'),
  onHotReloadNotAvailable: () => myLogger.log('No hot-reload :('),
  onHotReloadAvailable: () => myLogger.log('Yay! Hot-reload :)'),
  onHotReloadLog: (log) => myLogger.log('Reload Log: ${log.message}'),
  logLevel: Level.INFO,
);
