* Add support for the new encryption protocol
This adds support for the new TP-Link discovery and encryption
protocols. It is currently incomplete - only devices without
username and password are current supported, and single device
discovery is not implemented.
Discovery should find both old and new devices. When accessing
a device by IP the --klap option can be specified on the command
line to active the new connection protocol.

Display an error if both --alias and --host are defined to avoid ambiguous target device:
```
❯ kasa --host 123 --alias 123 state
Usage: kasa [OPTIONS] COMMAND [ARGS]...
Try 'kasa --help' for help.
Error: Use either --alias or --host, not both.
```
Also, use `click.BadOptionUsage` consistently for other errors, like when only `--username` or `--password` is given.
Several KASA devices seem to have pretty strict buffer size limitations on incoming/outgoing data transfers.
Testing on KL125-US and HL103 has shown that sending a request size larger than about ~768 bytes will immediately crash the device. Additionally, a query that generates a response larger than ~4096 bytes will crash the KL125-US. I was unable to generate such a large response to test the HL103.
The KL125-US will only return such large queries when its monthly usage stats have been populated. This means that a new bulb would work fine, but after a month of data collection the bulb would break the 4K limit and start to crash.
To work around this issue, an estimated worst-case response size is calculated before sending a request by summing up all modules estimated response size. If the estimated size is greater than the device's max_response_payload_size then the query will be split into multiple queries.
This PR implements splitting queries expected to have large responses and also removes the module 'skip list' which was a previous workaround to the crash (which worked by simply reducing the number of modules queried, which prevented the overflow) since it is no longer necessary.
This PR does not attempt to address the "input buffer size limit." Thus far this limit has not been an issue.
* Add plumbing for passing credentials as far as discovery
* Pass credentials to Smart devices
* Rename authentication exception
* Fix tests failure due to test_json_output leaving echo as nop
* Fix test_credentials test
* Do not print credentials, fix echo function bug and improve get type parameter
* Add device class constructor test
* Add comment for echo handling and move assignment
asyncio.wait_for has some underlying problems that are only fixed in cpython 3.12.
Use async_timeout instead until the minimum supported version is 3.11+ and it can be replaced with asyncio.timeout
