v0.3.25: use dirigera 1.6.0 instead of local model patches (#67)

The integration now relies on the dirigera library 1.6.0 for things it used to patch around itself (PR #67 by @Leggin, who maintains the library). dirigera_lib_patch.py shrinks by about 120 lines.

• Lights: the library keeps the hub's colorMode, so the local LightX model is gone.
• Colour temperature: set through the library instead of a direct PATCH. Ranges reported in mireds (e.g. KAJPLATS, 153..454) now show up correctly in Home Assistant instead of as 454..153 "Kelvin", and requests are kept inside the bulb's range.
• Motion sensors and controllers: the library models are used directly, including MYGGSPRAY without isOn.
• Blinds stop: through the library's set_state(STOPPED).
• Outlets: selected by deviceType, so a GRILLPLATS whose metering half reports type: "outlet" no longer fails to load.

One behaviour difference: a bulb that accepts colour temperature but reports no min/max now raises the library's ValueError instead of sending an unchecked request. IKEA bulbs report the range.

Tested: full suite 113 passed with dirigera 1.6.0. On a real hub, colour-temperature changes on a TRÅDFRI colour bulb (2700 K, 4000 K, an out-of-range 6500 K clamped to 4000 K, and 3000 K confirmed in the hub's own state). Blinds stop is not tested on hardware; we have no blinds here.
