Allow custom JS code

[picklelo]

The user should be able to give a string of custom JS code that will be compiled to the top of the page.

I can also work on this. How would the feature look like in code? Sth like this?:

app = pc.App()
app.add_page(index, custom_js_scripts=[js_code_str_1, js_code_str_2])

Maybe add a pc.script function? and we can choose where the script should be placed.

Interestingly we have already had a pc.script. It looks to me it's a nextjs NextScript object.

I'll suggest we rename the pc.script to NextScript instead. I think this component is only used internally in the framework so it's probably fine. And create a Script component.

This would be an awesome feature to have.
