Add data for newly captured voice models

[lpatino10]

Currently, there's an issue where there are some new models which do not have associated sample audio or keywords. This is resulting in an error when users try to play the sample audio:

The models in question are:

• es-AR_BroadbandModel
• es-AR_NarrowbandModel
• es-CL_BroadbandModel
• es-CL_NarrowbandModel
• es-CO_BroadbandModel
• es-CO_NarrowbandModel
• es-MX_BroadbandModel
• es-MX_NarrowbandModel
• es-PE_BroadbandModel
• es-PE_NarrowbandModel

This PR just points those models to the same sample files and keywords used by the es-ES_BroadbandModel and es-ES_NarrowbandModel models for now, since the service team does not have real audio files ready for us to use.
