Handle filename on validate/pack command

[justkeepquiet]

Hi. When runningcommand validate/pack command, I would like to be able to get the XML filename in which there is an error.
For example like this:

Unhandled exception: System.Xml.XmlException: '<', hexadecimal value 0x3C, is an invalid attribute character. Line 12, position 44.
   at System.Xml.XmlTextReaderImpl.ParseAttributeValueSlowAsync(Int32 curPos, Char quoteChar, NodeData attr)
   at System.Xml.XmlTextReaderImpl.ParseAttributesAsync()
   at System.Xml.AsyncHelper.ReturnTrueTaskWhenFinishCoreAsync(Task task)
   at System.Xml.XsdValidatingReader._ReadAsync_Read(Task`1 task)
   at Vezel.Novadrop.Commands.ValidateCommand.<>c__DisplayClass0_0.<<-ctor>b__1>d.MoveNext() in F:\novadrop-master\src\tools\dc\Commands\ValidateCommand.cs:line 51

Hm, I hadn't tested what would happen if the XML is outright malformed. We should definitely print a more actionable error here.

Can you please open a feature request on the issue tracker: https://github.com/vezel-dev/novadrop/issues
