API changes

Added Proto.Promises.{CancelationSource, CancelationToken, CancelationRegistration} structs which can be used for synchronous cancelation callbacks.
Added optional CancelationToken parameter to Promise.{Then, Catch, CatchCancelation, ContinueWith, Progress, Sequence, NewDeferred}.
Changed Deferreds to structs with an implicit cast to DeferredBase (DeferredBase.ToDeferred(<T>)() to cast back explicitly).
Removed DeferredBase.Cancel, replaced with the cancelation token.
Removed Promise.{Cancel, ThenDuplicate}.
Removed Proto.Logger, replaced it with Promise.Config.WarningHandler.

Changed Promise.First to suppress rejections from any promises passed in that did not result in the rejection of the returned promise.
Change Deferred.Reject(null) to convert to a NullReferenceException on any T. This means Promise.Catch<T> will never give a null value. This more closely matches normal throw null; behavior.
CancelationSource.Cancel(null) now converts cancelation to a non-value. This mean if Promise.ReasonContainer.ValueType is not null, Promise.ReasonContainer.Value is also not null, and if Promise.ReasonContainer.TryGetValue<T> succeeds, the value will not be null.
Removed requirement to include Proto.Promises.Await for awaiting promises in an async function.
Check to make sure RethrowException is used properly, change to InvalidOperationException if not.

Deferreds are now structs, removing the memory overhead of classes.
Added a static cached Promise.Canceled() void in RELEASE mode.
When canceled, promises are now unlinked from their previous.
No longer check if promise is canceled when doing internal operations.
Removed internal skipFrame calculations since that's now handled in Internal.FormatStackTrace in DEBUG mode.
Pass by ref to pass large structs around internally more efficiently.
Less memory used in Promise objects with onRejected callbacks.
PromiseMethodBuilder caches stateMachine.MoveNext directly instead of lambda capturing.

Removed recursive type definitions so that Unity 2019.1.14 and older on .Net 4.X scripting runtime version will compile.
Removed PROTO_PROMISE_CANCEL_DISABLE preprocessor checks since cancelations no longer slow down normal execution.
No longer check for internal promise invoking when accessing Promise.{RejectException, CancelException}.
Renamed asmdefs to include Proto in the names. Removed Utilities.asmdef.

A Promise.Progress callback subscribed to a promise chain where the chain is broken by a cancelation token and continued with Promise.ContinueWith reports incorrect progress (introduced in v 0.9 with Promise.ContinueWith).
