/**
 * Create or update a file. The file store is backed by a Postgres table and S3 object.
 * If no 'contentType' is passed, it is inferred from the 'magic bytes' from the source.
 * Defaulting to a wildcard.
 *
 * By passing in an `allowedContentTypes` array via the last options object, it is
 * possible to validate the inferred content type. This also overwrites the passed in
 * content type.
 *
 * You can set `allowedContentTypes` to `image/png, image/jpeg, image/jpg, image/webp,
 * image/avif, image/gif` if you only want to accept files that can be sent by
 * {@link fileSendTransformedImageResponse}.
 *
 * If 'fileTransformInPlaceOptions' is provided, this function will call
 * {@link fileTransformInPlace}. Note that image processing is computational heavy, so
 * in a high-throughput scenario you may want to schedule a job which calls
 * {@link fileTransformInPlace} instead of passing this option directly.
