Use retrieveChecksum() instead of checksumEntireFile() in ES93BloomFilterStoredFieldsFormat. While individual bloom filter files are small, checksumming on every reader open adds up across many segments. We can safely defer verification since files are checksummed during merges. Also switch to using the slice reader for merges since it's already positioned correctly in the file.
