Cap the default size of the external operation thread pool to 10 or
the maximum number of available processors, whichever is smaller.
Set the minimum size of the thread pool to 1. Meaning that only a
single thread is used unless the node actually starts to use
`FlowExternalOperation` which consumes threads from this pool.

Deprecate FlowAsyncOperation and reimplement public versions FlowExternalOperation and FlowExternalAsyncOperation.
await added to FlowLogic to allow easy calling from both Java and Kotlin. There are two overrides of await (one for FlowExternalOperation and FlowExternalAsyncOperation).
Implementations of FlowExternalOperation return a result (written as blocking code) from their execute function. This operation will then be executed using a thread provided by the externalOperationExecutor.
Implementations of FlowExternalAsyncOperation return a future from their execute function. This operation must be executed on a newly spawned thread or one provided by a thread pool. It is up to developers to handle threading in this scenario.
The default thread pool (externalOperationExecutor) can be configured through the flowExternalOperationThreadPoolSize node config.
The current implementation leaves FlowAsyncOperation alone, meaning that any developers that have used it (even though it is internal) won't need to change their apps. If this was not concern I would delete it completely and replumb the state machine code. Instead, it has been marked with @DoNotImplement and executeAsync is annotated with @Deprecated

Adds support for understanding both Maps and Arrays
Irritatingly, whilst arrays are mostly serialized as lists, we cannot simply use a restricted List reader to deserialize them because there are subtle differences in the way we need to work out if its actually a restricted type or not. Rather than add a bunch of random logic into the factory method I've isolated it in the class hierarchy. So a little bit more code makes the implementations a lot neater. We also need to deal with the fact arras of unboxed primitives exist, which whilst Java really gets excited about, we don't need to care about. An int, is an int, is an int!.
Map support required we add a slightly better Value dumper, essentially the "key" component of the KV pair needs to be more flexible than a simple string when we're dumping out param:value pairs.
Testing
Added a lot more unit tests to both the ordered type notation code to ensure we build up the schema dependency struct in the correct order. Quite important as we rely on that in the composite factory to be strictly ordered to ensure we're not constructing a reader for a type we don't yet understand... and there were some small bugs in the version that predates this PR
Also added a lot higher level tests to ensure actual reading out of the blob works
