Add missing include and fix compilation on windows

In otbSARDerampImageFilter there is a missing include (otbVectorImageFilter) which causes otb CI to fail.

Also the master version of diapOTB doesn't compile on windows (MSVC) because of a C-array with a length defined at run time, which is non standard in C++, even it is allowed by gcc.

This MR adds fixes for these two issues.
