Warn on unknown options

[LinusU]

It would be very good if we could output a warning when passing in any option that we don't recognise.

We can't start throwing just yet since that needs to be in the next major bump, but that is the behaviour that I would most prefer.

anything pending here?

anything pending here?

interested too, here. Yet I propose a change on that enhancementproposal 👍

• Dynamically changing destination folder path, instead of
• Dynamically changing destination folder name
• paths being relative to the root folder set as destination root : so with a new config parm called destination_root, instead of destination

@LinusU This could be a good feature to add into #399 (which is not really related to the stream API but I don't think there's an issue tracking the next major version specifically)

This is an interesting one 🤔

I think that personally my stance on this have changed, especially now with the prevalence of TypeScript. I don't know of any other library that does this kind of runtime validation on passed in options 🤔

With modern editors (VS Code, Atom, etc) this will already be warned directly in the source code when adding an option that doesn't exist.

Open to hear what other people think!
