feat: Added new docs when using bundlers

[lsegurado]

Related to #1855

I'm adding a new command:

• add as a new file in src/api (and src/commands if necessary)
• add command to src/index.js
• update __tests__/test-exports.js
• create a test in src/__tests__
• document the command with a JSDoc comment
• add page to the Docs Sidebar website/sidebars.json
• add page to the v1 Docs Sidebar website/versioned_sidebars/version-1.x-sidebars.json
• if this is your first time contributing, run npm run add-contributor and follow the prompts to add yourself to the README
• squash merge the PR with commit message "feat: Added 'X' command"

I think that different bundlers have better ways to include a Buffer object than adding it to a window object directly, but this is better than nothing.

Thanks for your contribution.
