/**
* Create a new FileFormatConverter, using old or new converters.
* This function looks for converters in the 'converters' table in the db.
* $converterVersion can be "legacy", "latest", or something like "1.0.0".
* In the first case legacy converters will be used; in the second case,
* the latest version of new converters will be used; in the third case,
* this function will look for the converters with the provided version,
* and if not found will use the converters with higher but closest version.
* Version check is done on the conversion_api_version field of the
* converters db table; new converters are expected to have a value like
* "open 1.0.0".
