Refactoring to logically separate component modules in order to make it easier to develop tests, metrics, tracing, etc.

Adds some basic benchmarking, stress tests. They still need to be properly examined to ensure they are testing the correct properties, but fit for "good enough". Implements the HybridChannel type, which features a channel buffer that can withstand overflows. It does so by providing a dequeue behind a mutex. Without overflow, will push messages into the lock free ArrayQueue implemented by crossbeam_queue; when that buffer fills, will use the locking portion provided by the Mutex<VecDequeue>.
In the future we can even further optimize this, perhaps with some linked list implementations of lock-free channels, but, like the benchmarks, this fits the "good enough" bar for now.

Did not like the requirement of a tokio runtime and async/await. Rewrote
to use lock free queues (`crossbeam_queue::ArrayQueue`) as the basic
primitive to enable a runtime consisting of many pseudo-processes that
can pass messages to each other.

Introduce a typed `ActorRequestSender` connection handle for actors and harden the `Error` type.
- src/lib.rs: add `ActorRequestSender<A>` wrapping `mpsc::Sender<ActorRequest<A>>` with async `send`, `Clone`, and `From` impls; expose it via new `Handle::get_connection()` so callers hold a lightweight standalone connection to an actor
- src/lib.rs: route `Handle::send` through the new sender and store `tx` as an `ActorRequestSender`; drop the `Unpin` supertrait bound from the `Actor` trait
- src/error.rs: turn the `Error` type alias into a newtype struct, gate `convert_err` as `pub(crate)`, and add `From<T: AsRef<str>>` plus `ToString` impls
- examples/hello.rs: switch `Greeter::spawn` to method-call syntax (`Greeter.spawn(&rt)`) to match the updated API
- README.md: rename the project heading from "about" to "swactor"

Skeletal actor framework. Somewhat unweildy, needs a message box, a better runtime, and different channels. However, hello world example works
