Bug#951991: bali-phy: FTBFS: detected.hpp:52:7: error: invalid use of incomplete type ‘struct nlohmann::detail::detector, nlohmann::basic_json, std::allocator >, bool, long int, long unsigned int, double, std::allocator, nlohmann::adl_serializer>&, ptree>’

[Benjamin Redelings]

I pushed a new version (3.5.0.1) to salsa.

It builds on my machine with pbuilder and has only two minor lintian 
warnings (empty directory, imaginary(?) misspelling).

I had to update the copyright file because I'm using the immer library, 
which is under BSL-1.0.
