Big stats file cannot be loaded via fs function

[Yexiaoxing]

If any of the generated webpack stats file is bigger than 500M, the built-in fs.readJSON does not work, and throw error:

Cannot create a string longer than 0x1fffffe8 characters

A possible fix is like webpack-contrib/webpack-bundle-analyzer#423 which uses a chunked method to load the JSON.

@Yexiaoxing, thanks for opening the issue! The error has been shared before, and I plan to add support for large files on the next major version (#2118).

Until then, I recommend optimizing the webpack stats output. You can follow this guide to output only the data required by bundle-stats: https://relative-ci.com/documentation/guides/webpack-stats/webpack-stats-plugin/#optimize-the-webpack-stats-json-file-size.

If you get the chance to use the filter, will be great to hear how much the output changed. In the past, i noticed 90% decreases.
