Fixes #524. Upgraded NuGet dependencies:

 GitInfo from 2.0.15 to 2.0.20
 Microsoft.NET.Test.Sdk from 15.8.0 to 16.0.1
 NUnit from 3.10.1 to 3.11.0
 NUnit3TestAdapter from 3.10.0 to 3.13.0
 Microsoft.Extensions.Configuration.EnvironmentVariables from 2.1.1 to 2.2.0
 Microsoft.Extensions.Configuration.Ini from 2.1.1 to 2.2.0
 SharpCompress from 0.22 to 0.23

With the upgrade to the latest SharpCompress, the handrolled tar symlink support in BAM Core has been deleted. All tar extraction operations now go through SharpCompress.
