Accept the unprefixed import library name on Windows

The example builds searched only for _cspimpl, but CMake applies the
leading underscore to the module and not to its import library, so the
wheel ships csp/lib/_cspimpl.pyd alongside csp/lib/cspimpl.lib. Every
Windows example failed to configure with CSP_LIBRARY-NOTFOUND.

Search both names, preferring the underscored one if a build ever
produces it. Confirmed against the wheel from this branch: cspimpl.lib
is present and exports both the C API symbols and the C++ symbols the
older examples link.
