New device support

Improvements for existing devices

Hysen HY08ACF fix fan_mode, use valve state as hvac_action with additional cooling value, remove non-working child lock type switch, just report it as an attribute of child lock (#343)
RGBCW, Moes, Digoo lights: rename effects to original Scene and Music names.
T5E WF thermostat: convert non-working fault sensor to a binary sensor and put raw fault code as an attribute of the main entity, as with other devices
Blitzwolf humidifier: fix spelling of name (PR #364)
M027, Zemismart curtains: assume dp 12 is fault, if available, as per similar Loonas curtain (#367)
Motion sensor light: add a switch for auto mode (#282)

Bump tinytuya dependency from 1.9.1 to 1.10.1
poll the devices once during startup, and pass the initial state to HA so they do not appear unavailable until startup is complete
add protocol version 3.5 support (#359)
calculate retry attempts needed based on number of protocols supported
water_heater: remove some extra copy and paste methods from climate that are not relevant for water_heater.
add more generic config file tests to catch typos and missing required dps for different entities
inform HA when devices become unavailable (PR #362)
add an option to poll devices (speculative but unsuccessful fix for #338)
avoid trying to change readonly properties that are linked through conditional constraints (#282)
default the address when adding new devices to "Auto", which is handled specially by tinytuya
use higher level new tinytuya API for sending (speculative but unlikely fix for #338 and #372)
cover: consider positions within 5% of the end to be at the end (#373)
Documentation fixes
Avoid misleadingly using the term add-on to describe this integration.
