The compat library added an `early-semver` versionScheme which means
that 1.0.0 is marked as binary incompatible with any version lower
than 0.9.1 - even though it's not.
For example:
```
[error] (update) found version conflict(s) in library dependencies; some are suspected to be binary incompatible:
[error]
[error] * org.scala-lang.modules:scala-java8-compat_2.13:1.0.0 (early-semver) is selected over 0.9.0
[error] +- com.github.blemale:scaffeine_2.13:4.1.0 (depends on 1.0.0)
[error] +- com.typesafe.akka:akka-actor_2.13:2.6.14 (depends on 0.9.0)
```
The `scalaModuleMimaPreviousVersion` has been set to `0.9.1` in the project, so upgrading
Akka to this should allow it to work with a lot of other libraries who have already done
the major update (supports Scala 3) to 1.0.0.
Changes:
* Private constructor for case class means private apply in Scala 3
* Logger class with Any instead of wildcard where needed
* Explicit import of internal implicit conversion import SinkToCompletionStage
* Hopefully source and binary compatible Scala 3 signature for GraphApply.create methods
* ZipLatestWith leaking private type
* Auto apply-to-lambda made explicit
* Internal async callback event class covariant
* Hub leaking private type
* Remove cycles in stream Buffer classes
* Avoid cyclic import in ResizableMultiReaderRingBuffer
* Safe cast of Subscribers
* Explicit import of internal implicit conversion SourceToCompletionStage
* Ambigous field name and method
* recover delegates using PF from javadsl not inferred, made explicit
* TcpStage completing promise with wrong type
* Collect aggregator empty value cannot be underscore with type ascription
* Some type alias shenanigans in QueueSink removed
* Explicit type on effectiveMaximumBurst in Throttle
* Override method return type not inferred in GraphInterpreter
* MutableCollectorState.accumulated getter got wrong type somehow
* TLS actor fallback case only applicable to null
* Some internal unchecked pattern matching removed
* Ok that createGraph is not present in Java API
* Separate impl per language for implicit actor system apply
* Move more release instructions to the template
