This release has initial support for chia 1.3 changes.

https://www.nuget.org/packages/chia-dotnet/1.0.0-beta.1.3.6

• Changes to existing endpoints are incorporated
• Creating a CAT wallet tested
• Testing trades and offers still in progress
  • Until this PR is merged (Chia-Network/chia-blockchain#10571) supply both a start and end to TradeManager.GetOffers. Otherwise it will fail.
