Add support for MAL315HA

[CloCkWeRX]

https://grid-connect.com.au/document-tag/mal315ha/
Not supported by the main tuya integration, works well when set up manually as a binary sensor.

https://templates.blakadder.com/arlec_MAL315HA.html

For some reason, reports itself as a "dj." category device; potentially representing 'light switch on/off' (weird full stop though)
https://developer.tuya.com/en/docs/iot/dj?id=K9i5ql3v98hn3 doesn't really cover it.

App UI suggests it supports more

Not sure if it's possible to add as it may? has incorrect category and can conflict with dj codes if you setup the cloud then download the device diagnostics and post it it should contains the device dps_data

Hmm, okay, the error message mislead me a bit; it self reports as a broad kind of light (dj) instead of a more specific motion sensor

Your device cloud info is missing some objects such as dps query, from the dps strings it should exists. ensure when download the diagnostics internet is on? an example of dps object
