Errors of missing std.conv imports

[zorael]

Manjaro/Arch x86_64, dmd 2.091.0, ddox 0.16.13 fetched and built via dub.

My project uses x:ddoxTool "scod" for generating documentation and it stopped working at some point recently, perhaps with updates to diet-ng.

/usr/bin/dmd failed with exit code 1.

Not sure whose bug this is bug filing it here since building ddox is what throws the error.

Changing the std.conv import in source/ddox/api.d to a public one works around the issue, but likely isn't ideal.
