Fund: gen: derive mappings with parameters

Description

PR #374 removed mapping for Photo -> InputPhotoFileLocation due to InputPhotoFileLocation requires ThumbSize field.

But gotdgen can generate mapping like AsInputPhotoFileLocation(thumbSize string) *tg.InputPhotoFileLocation, where thumbSize passed by user.

mappableFields returns possible As mapping.

Why does "Fund on completion" require GitHub login?

When is the invoice due for "Fund on completion"?

What happens if the issue is never completed?

Do I get any extra benefits by funding?

Do I get progress updates?

Do I get a reward?

Is rewards guaranteed?
