New version of FastReport .NET 2019.3

In the latest version of FastReport .Net 2019.3 we added a new object - digital signature, that allows adding place of signature after exporting it to PDF.
We also added property that allows aligning picture inside the PictureObject.
You can now change fonts in query editor.
And we fixed that critical bug that led to memory leak and infinite loops.
