Modernize ToDataTable Package and Update Dependencies

[danielmallott]

I use this package in a project I have (https://github.com/danielmallott/lego-data-set-loader), and Snyk has been bothering me about the security issues with System.Data.SqlClient, so I took it upon myself to make some version updates.

This PR accomplishes the following:

• Updates ToDataTable.csproj to target NetStandard 2.0, in line with Microsoft guidance on building libraries
• Updates other projects to target Net 10.0
• Replaces System.Data.SqlClient with Microsoft.Data.SqlClient, in line with Microsoft guidance
• Removes unused HyperDescriptor packages, which targeted only .NET Framework
• Updates other packages to most recent version available
• Migrates to slnx solution file format
• Updates ToDataTable.Benchmarks to specifically reference the Release version of its dependence projects
• Updates Nuget package version to 1.0.0, to reflect targeting update

The unit tests and benchmark tests both pass.
