Update to support zigpy 0.70.0

[puddly]

We've made a few API changes in zigpy and this package will need updates to continue working:

1. def close -> async def disconnect.
2. All radio libraries should let zigpy configure the serial port flow control settings.
3. Utilize packet.priority.

@DamKast Do you want to transfer this package to the zigpy organization so we can keep this package updated? I'd eventually like to include it as an option in ZHA once we figure out a way to get firmware publicly built. If not directly for the nRF52840, I think we probably could do so for the Espressif Zigbee stack: https://github.com/andryblack/esp-coordinator

@puddly Sure, I can transfer this package to the zigpy organization. What are the steps to do this?

@DamKast remember to also add zigpy admins/owners as Maintainers of the matching zigpy-zboss project on PyPI as well:

• https://pypi.org/project/zigpy-zboss/

i.e. same Maintainers as the example the zigpy-znp project on PyPI:

• https://pypi.org/project/zigpy-znp/

Any progress on transferring zigpy-zboss repository (and the matching project on PyPI) to zigpy organization/admins on GitHub?

PS: Off-topic but think this might also be even more relevant now to the open-source Zigbee community at large because Zigbee2MQTT (Z2M) also added ZBOSS support and interestingly they implemented code based on a port of zigpy-zboss -> * https://www.zigbee2mqtt.io/guide/adapters/zboss.html in a new adapter for zigbee-herdsman -> https://github.com/Koenkk/zigbee-herdsman/tree/master/src/adapter/zboss
