Implement mandatory instance in LwM2M definition

[MLopezJ]

Same as MultipleInstances https://github.com/MLopezJ/LWM2M-JSONSchema/issues/11 , the mandatory property from the registry should be considered in the type definition of the LwM2M object.

<LWM2M xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.openmobilealliance.org/tech/profiles/LWM2M-v1_1.xsd">
  <Object ObjectType="MODefinition">
        ...
        <MultipleInstances>Multiple</MultipleInstances>
        <Mandatory>Mandatory</Mandatory>
        <Resources>
            <Item ID="0">
                           ....
            </Item>
    </Object>
</LWM2M>
