dumpFileVersion(dump: { fileSize?: number; createdAt?: Date; updatedAt?: Date; }): string
Returns a file dump's version, which the file and thumbnail URLs carry as
?v=: the frontend's dumpFileUrl and dumpThumbnailUrl, and the digest's
thumbnails. It changes whenever the file may have, so the file and thumbnail
routes cache a URL naming the current one for good and revalidate any other.
Without its dates, a dump gets a version no route serves as current.
