Cannot initialize hidapi

[JanKoudijs]

Hi @dannydulai,

When I try to run the PowerMate extension it throws an error immediately:

bash-4.3# node .
/root/.RoonExtensions/roon-extension-powermate/node_modules/bindings/bindings.js:91
        throw e
        ^

Error: cannot initialize hidapi (hid_init failed)

I found another report of this issue, where the suggestion is made to update to a newer version of node-hid. I saw that the repository you forked node-powermate from already has this update. By switching to this node-powermate repository the extensions is running again, but I cannot verify if it works (don't own a powermate).

Maybe you can check if an update of node-hid would be a sensible update.
