Is there an existing issue for this?

I have searched the existing issues

Summary

Like the title suggests, make base64 encoding and decoding available to the pre-request scripting environment.

Why should this be worked on?

I confess I am unaware if btoa is in the ecmascript standard or not, but seeing as how its been in every execution environment I ever tried to use it in, I was surprised when it wasn't available here.

Been trying to use some combination of Buffer/CryptoJS, btoa and even seeing if it's somehow possible to import libraries into the pre-request scripts of Hoppscotch...
1h later I found this issue (Google has indeed been losing qualities...); sad that you can't do base64 encoding/decoding, but I'm happy there's a PR already made to add these functions in.
