[feat] Use new restoreNVM API to restore NVM backups

[kpine]

Describe the solution you'd like

Z2M currently uses the restoreNVMRaw API to restore a backed up NVM. This API requires the the source and target controller NVMs are compatible. node-zwave-js v8.9.0 added a new restoreNVM API which automatically converts the NVM backup to the correct target format. Using the new one would allow users to backup from a 500 and restore to a 700, for example.

Unless I'm missing something, there doesn't seem to be any reason for applications to use restoreNVMRaw anymore with this new API available.

@kpine Thanks! It's a quick fix, just need to change the api name
