src/Data/Serialization.h fails to compile with Boost 1.58.0

The function boost::serialization::stl::load_collection no longer exists, neither do archive_input_seq nor no_reserve_imp

I don't understand why load_collection has been deprecated, especially since save_collection still seems to exist. The work-around at the moment is to use Boost 1.56, which has both defined.

It seems that you are relying on internals of Boost.Serialization that are not part of the public API and so have changed in the 1.58.0 release. These details have apparently changed again in Boost 1.59, which needs a different approach (but apparently still using non-public interfaces) as shown in boostorg/property_tree@52a99b5

I have no idea what the "correct" approach is, using only a stable public API.
