Review comment:
yep, this works; also, makes sense to me - we should not proceed to read
a bloom filter header (including seeking its offset), if there is no bloom
filter in the file; this can be checked via the `bloomFilterOffset` variable -
it can't be 0 if a bloom filter is present; and if no bloom filter, it can be 0
only.
I'll remove the TODO comment.
