Default FreeImage.dll binary requires VCOMP140.dll

[sherlock1982]

FreeImage.dll includes LibRawLite library.
It is compiled in x64 variant with OpenMP support.
It is not available on Windows Server 2016 & Windows Server 2019 out of the box unless you install vc_redist.x64.

So someone needs to recompile it without OpenMP or make a note that generally Visual Studio redist (2015 I suppose) is required here.

Updated readme to reflect this dependency. Feel free to send a PR if you feel strongly that OpenMP / LibRawLite / MSVCR should not be required.
