Open.ChannelExtensions Versions Save

First Channels V7 release.

Final release for Channels V6.

Added snupkg. Updated references with some improved instances of .ConfigureAwait(false).

• Although .NET Core 3 has IAsyncEnumerable<T> ReadAllAsync<T>(), I decided to expose .AsAsyncEnumerable() as an alternative for .NET Standard 2.1 users.
• .ToChannel<T>() extension for AsyncEnumerable<T>.
• .Batch() and .Join() extensions better leverage on-demand requests from the source channel.
• singleReader optional parameter is commonly available.
• deferredExecution optional parameter exposed to guarantee methods can yield to the caller.
• Nullable support built in.
• Expanded test coverage.
