Updated extension SqlDataInspector to 0.7.1

[ernstc]

Changes

• Added column information such as nullability (indicated with a question mark "?"), size and precision.
• Added new feature for copying all the values of the selected column and their corresponding counts. Copied values can be pasted on Excel for further analysis.
• The filters panel is now collapsible. This makes the usage of the workspace area more efficient when no filters are defined.
• Values for columns of type date, datetime, datetime2 and datetimeoffset are sorted descending by default. This can be useful for monitoring columns with datetime for creations, updates and similar.

Fixes

• Fixed a bug in the live monitoring that was preventing the data from refresh.
