Bug#1058948: missing dependency on boost-url

[Matthias Klose]

Package: src:boost1.83
Version: 1.83.0-1
Severity: important
Tags: sid trixie
libboost1.83-all-dev is lacking a dependency on libboost-url1.83-dev.

what is the rationale for add the new deps to libboost1.83-all-dev, and 
not libboost1.83-dev?
