[ANN] mdds 1.7.0 on master

Hi,

neither of which are AFAIK used in the LibreOffice codebase, this is a
low risk upgrade.

? Why does your commit on master then remove multi_type_vector stuff?

That could possibly be because they are obsolete and now not needed,
which means there _IS_ in stuff LO uses except trie_map and
packed_trie_map - namely at least in multi_type_vector.
