Collecting into a vec and then using the same reference seems preferable.

Sorry for the delay in responding to the review comments, I instead got busy, uh, playing the game instead. 😅 |

I'm not sure I know what the behavior of this should be for structs that don't have a collect_with, and I'm a little wary of every impl having this extra field and functionality not intended for it.
If there was a cleaner break in impls that have the collectd_with attribute and those without, I'd be comfortable merging this to minimize any potential downsides.

This fixes issue #232, although I can't exactly guarantee that performance will be as good as it was before.
I've done some local testing with melted saves via a modified
eu4save, using this for collecting trade node data. I haven't done any testing with binary saves, so I can't confirm whether or not it works there.
