* Manager

- Changed from using D's dynamic arrays for the array of `Queue` objects to using an `SList!(T)` where `T` is the `Queue` type
- Implemented `getQueue(ulong)` which returns the `Queue` object with the matching id/tag, else throws an instance of `TristanabaleException`
- Implemented `registerQueue(Queue)` which will attempt to add the provided `Queue` given that a queue does not already exist with the provided queue's id; if that is the case then an instance of `TristanableException` is thrown

Queue

- Made the constructor take in the `ulong` queue ID
- Made the constructor publically accessible
- Implemented `getID()` which returns the `Queue`'s id as a `ulong`

- `getQueue(ulong)` now calls `getQueue_nothrow(ulong)` with the same id
- Implemented `getQueue_nothrow(ulong)` which returns the `Queue` if found, `null` otherwise
- Added `getDefaultQueue()` which gets the default queue by calling `getDefaultQueue_nothrow(ulong)` with the same id
- Added `getDefaultQueue_nothrow(ulong)` which returns the default queue as a `Queue` object if it exists, else `null`
- Added `setDefaultQueue(Queue)` which sets the provided queue as the default queue (i.e. the queue where messages tagged with a tag of a queue not registered will be dumped into - if the default queue is set)

Watcher

- Set the worker thread, `watch`, in the constructor
- Added a TODO relating to checking if the socket read succeeded or not
- Added a debug print for the received `TaggedMessage` post-decode
- Extract the tag of the message and find the matching queue (potentially, if it exists)
- If the queue exists then add the `TaggedMessage` to said `Queue`
- If the queue doesn't exist then, get the so-called "Default queue", if it doesn't exist don't do anything, if it does then enqueue the message (the `TaggedMessage`) to said `Queue`

Unit test

- Added a unit test (WIP) for testing the `Manager` and `Watcher` mechanism
- Updated unittest to test the `getQueue_nothrow(ulong)` method

Package (`tristanable.manager`)

- WIP: `shutdown()` method

* Manager

- Added unittest for `getUniqueQueue()`
- Typo fix

* Manager

- Removed empty unittest

* Config

- Added new module `config`
- Added new type `Config` which is used for configuring an instance of `Manager`

Unit tests

- Sleep for 4 seconds instead of 2 before the server sends the two tagged messages
- Send a messae tagged with tag `42` before that of the one tagged with `69`
- Register a queue with tag `42`

- Added assertion to ensure the tagged message of `69` is indeed received correctly (tag AND payload)

* Queue

- Added documentation for the constructor `this(ulong)`
- Fixed issue #5

Unit tests

- The `==` operator on strings does some normalization stuff which results in differing byte sequences and therefore inequality (see the `"Cucumber 😳️"` case), therefore casting to `byte[]`
- Send another message tagged with `69`
- Fixed comment for server code sending tagged `42` message
- Call `manager.stop()` right at the end of the unit test

* Watcher

- Added package-level accessible `startWatcher()` method which calls `start()` for us
- Added some debugging prints which will now only be compiled-in during unittest builds
- If the bformat `receiveMessage(Socket, ref byte[])` method fails (returns `false`) then exit the loop, only continue decoding if it is `true`
