getAssetVersions

void getAssetVersions(
    const std::string& assetId, 
    StringVector& ret
)

Get a list of available versions for an assetId for an artist to select from.

The returned versions must be a list of strings, but they are not limited to numeric version numbers. Artists could select from labels or statuses like "best", "latest", or "official".

If the given assetId is not valid, or has no versions this can return immediately with no changes to ret.

The ret string vector is a regular std::vector class. Use the push_back to append entries.

This version list is only used by the Importomatic node when users click on the version column. Importomatic will pass the selected value to resolveAssetVersion.
