No simple way to parse from std::istream

There should be a quick and convenient way to parse JSON from `std::istream`. E.g. ```c++ std::ifstream f("path/to/file"); auto jv = json::parse(f); ```

[This experiment](https://github.com/s9w/cpp-lit) claims that including `boost/json.hpp` results in _build_ time of ~1500 ms, while including `nlohmann/json.hpp` — only ~900 ms. We could investigate this to see if there's anything we...

Given that this in a test, we probably can just remove initializer list with something more explicit...

Fix tests failing for 32-bit targets

When an integer is converted to a floating point type which cannot hold it without loss of precision, the conversion is implementation-defined. This apparently means, that the conversion can result...

In particular ```cxx std::vector< json::value, json::polymorphic_allocator < json::value > > v; ``` would result in a linking error if built in non-standalone mode.
