some bugs?

pure-lua-bloom-filter/bloom_filter.lua

Line 96 in 14bc42e

for i = 0, self.bits do

should be

for i = 0, self.bits do

-->

for i = 0, self.bytes do

pure-lua-bloom-filter/bloom_filter.lua

Line 42 in 14bc42e

for i = 0, bf.bytes do

start for `1` would be better
for i = 1, self.bytes do

【same above】

another one:

 local b = xxh32(val, i) % self.bits;

should be

local b = xxh32(val, string.len(val), i) % self.bits;
