ADD DDF for Legrand 067755 Wireless Scenes Command

[Smanar]

With the @Didier3L help, See #6081

"eval": "Item.val = (ZclFrame.at(0) + 18) * -1000 + 2"

The formula is not realy clean, but it work and don't want to break it (haven't the device to test). And can't use legacy code as legrand reverse the payload.

Something interesting, the device support 0x0020 and 0x0021 attribute on the cluster 0x0001, but it seem only the 0x0020 can use reporting (not investigate)

It seem too the device don't need bind on the cluster 0x0005 (and battery reporting is probably useless too as it have worked using the bad one)

Like some Legrand stuff (all scene switch), group feature are disabled for the moment by security (some device recreate group in loop mode)

Hello, is there an extra space in the file name?

[Smanar]

Yeah typo ^^, I have edited the file name just under, it's the PR called "name change" (to remove this space).
Have too changed the cluster used in the uniqueID, to have the scene cluster displayed (as it's the only one cluster used by the device)

The final result is here https://github.com/dresden-elektronik/deconz-rest-plugin/pull/6096/files

About the cluster change, when the DDF will be officially in your version, better to delete the DDF you are using ATM and re-include the device to use the official DDF, I don't think it will impact jeedom, as it use device id and not uniqueID (But I can't be sure)
