Bug report

The same bug that webpack/webpack-cli#2190 fixes. The issue here is if webpack stats object is large enough you can no longer just call JSON.stringify on it, otherwise you get errors along the lines of RangeError: Invalid string length.

The fix here is to stream the JSON serialization rather than doing it at once. Fixing this might be tricky without making a breaking change to the plugin API since I'm not sure how it can be compatible with the current opts.transform

The plugin supports promised-based transforms that you can use JSON streaming. Here's an example: https://github.com/FormidableLabs/webpack-stats-plugin/blob/main/test/scenarios/webpack5/webpack.config.js#L172-L196

Ahh, gotcha, the trick here being not using the file output from webpack-stats-plugin (emit: false) and just doing it yourself. Thanks for the pointer!
