Include `getDataBuffer` in javascript reference

[GlennOlsson]

I have checked the following:

• I've searched existing issues and found nothing related to my issue.

This feature

• blocks me from using Bruno
• would improve my quality of life in Bruno
• is something I've never seen an API client do before

Describe the feature you want to add, and how it would change your usage of Bruno

I needed to get the raw data (not as string) from the res object in a Post Response script. I did not find any documentation about it, but solved it using the getDataBuffer I saw in bruno-response.js. Would be great if this could be included in the Javascript API reference in the future

Mockups or Images of the feature
