Proper check metadata size on lower boundary

[asb-72]

If total_size is less than block size, computed size will be zero, fix it.

This should fix an issue where total_size being 16384 results in size becoming 0 right?

Yes, if total_size is less or equal to 16384, then the size becomes 0.

And further in the code the slice is equated as self.info_bytes[0..0]
