Support Xcode 13 / iOS 15

Fixes it so it can compile correctly for the latest version of Xcode / iOS SDK.

Code that directly creates a Bluejay.CharacteristicIdentifier from a CBCharacteristic needs to change to accommodate the fact that initializer is now fallible due to changes in the optionality of CBCharacteristic.service

Also includes a few smaller changes:

• Add setting to broadcast errors sent to cancelEverything to all listeners.
• Fix problem with timeouts in writeAndAssemble not working as expected if partial data is received
• Fix problem with the queue not restarting after transferring bluetooth state back to Bluejay

Hot fix for not restarting the queue when using the "Use" start mode

v0.8.8

Swift Package Manager

Added support for Swift Package Manager.

Support Xcode 11.3.1

Bumped minimum iOS target to 11 and recommended Xcode to 11.3.1

Update to Swift 5

Updated Bluejay, demos, and XCGLogger for Swift 5 and Xcode 10.2.1. Only hiccup was that jazzy doc seems broken with Xcode 10.2.1, so I couldn't update the jazzy documentation, but the README on GitHub is fine and updated.

Fix crash when making a Bluejay call right after an explicit disconnect

Failing a queueable requires updating its queue, and therefore requires the queueable to have a reference to its queue. The disconnection-is-queued failure block is relatively new, so I didn't catch the new requirement - that is to shuffle the queue assignment to the new starting point of the add call.

See #202 for more details.
