Adjust read timeout with corebluetooth to 10s

5s would result in quite a few random failures with
HomeKit BLE devices because the device would have to
process a large dump of fragments which make it slow
to respond

Fixes Jc2k/aiohomekit#111

Example of code that slows down the device with many
encrypted writes before waiting for a read
