Previously, we had WBFS and CISO which both returned an upper bound of the size, and other formats which returned an accurate size. But now we also have NFS, which returns a lower bound of the size. To allow VolumeVerifier to make better informed decisions for NFS, let's use an enum instead of a bool for the type of data size a blob has.
