Support .NET 5 for EPPlus SDK and package as a .nupkg.

This change:
- Adds an SDK-style project for EPPlus, which is multi-targeted
- Drops support for the RIPEMD-160 hash, which is not supported in
  .NET 5. This is only used for (older) encrypted Excel files, which we
  don't support anyway.
- Adds Nuget packaging support for EPPlus

To generate the .nupkg, run:
dotnet pack EPPlus/EPPlusSDK.csproj -c Release
