Update Z-wave products.xml for additional Everspring HSM02 id values

My Everspring HSM02 gives a product ID of 0002.  There already exists an entry for this devices in the Z-Wave database but for product ID 0001.  Mine appears to be identical to the existing everspring/hsm02.xml, so I've just modified products.xml to use the existing hsm02.xml for product ID 0002.

Perhaps a different ID value for the north american frequency? 
You don't need to add the whole new <Product> section - to add a new reference, you can just add the lines -:
```
<Reference>
<Type></Type>
<Id></Id>
</Reference>
```
below the existing reference section.

Can you update this to that format please?
