2sic Imageflow Oqtane module middleware

Changes

• update dependencies Oqtane 4.0.0, Imageflow 0.8.1

Because nuget package with dependencies for all runtimes is very big (27 MB) separate smaller packages are created for different platforms.
Recommendation is to install only packages that targets platforms in use.
Installing more packages in same oqtane installation will effectively append runtime dependence from last package.
