param_package: Use std::unordered_map's insert_or_assign instead of map indexing

Browse source 
This avoids a redundant std::string construction if a key doesn't exist
in the map already.

e.g.

data[key] requires constructing a new default instance of the value in
the map (but this is wasteful, since we're already setting something
into the map over top of it).
