ArgumentException when using --package

[loop-evgeny]

Same error as #32, but I'm not using Central Package Management. dotnet-depends version 0.70 on Windows.

md NewConsoleApp
cd NewConsoleApp
dotnet new console
dotnet depends --package test

Unhandled exception. System.ArgumentException: Value cannot be null or an empty string. (Parameter 'value')

Debugged the code a bit and turns out this is because --version (and also --framework) must be specified when --package is. Would be nice these were read automatically from the project file. Failing that, at least a good error message to tell the user that these are required.
