chore: remove dburl usage

dburl adds aliases for everything, which breaks if two schemes are similar enough (anything with `aws_` as a prefix broke scheme registration). It does not appear to add anything, so we'll drop that dependency.

Also remove go-jsonmerge, as this was refactored to use structs instead of byte manipulation...
