Feature request: URL argument to hide Operations and Recipe panes (embedded UI)

### Summary
A url argument to hide all but the Input/Output panes (and about button) could be useful to allow CyberChef to be embedded in other pages. This would make it a lot easier for users to use recipes from websites, as the operation and recipe panes can be quite confusing. A link could also be added to open the actual recipe in CyberChef seperately (to edit the recipe).

### Example

Page shown is at https://fileshare.infra.link/Numberwang/, but due to XSS I can't hide these panes from the parent page, so the screenshot shows what happens if you remove the panes and the notice.
