Parallel generation - are multiple .start()'s needed?

[actuallymentor]

Thanks for this wonderful package!

I'm generating two pdfs in the following approximate manner:

const pdfWithCover = new pdf( {...} )
const pdfWithoutCover = new pdf( {...} )

await pdfWithCover.start()
await pdfWithoutCover.start()

await Promise.all( [
	pdfWithCover.build(),
	pdfWithoutCover.build()
] )

await pdfWithCover.close()
await pdfWithoutCover.close()

Does this introduce overhead by calling two .start()'s or is that inconsequential? Is there a resource-optimal way to do this as scale? (e.g. generating 100 pdfs).

Thank you!

Multiple starts are needed for this. But it might make sense to have a reusable puppeteer instance, which will require a change to the library.
