add stats for xxhash and fnv upto 100M

It would also be useful to know how the benchmarks compare

@dashpole added a summary in .log files for fnv-1a 32, fnv-1a 64 and xxhash-64 , let me know if you need anything else if I am missing something here. Does the approach looks okay? I want to do more benchmarking for collision and other resource benchmarks.

For background, while working on this I wrote a go Fuzz test which was similar to yours that generated a random attribute.Set, and added it to a map[uint64]attribute.Set. I didn't find a collision with fnv-1a after 4 billion. So i'm not sure how high you will need to go, but 100M is probably an order of magnitude or two too small, at least for a 64 bit hash.

My ask for benchmarking was to implement hashing for attribute sets using xxhash in a branch, and compare the BenchmarkNewSet in the attribute package before and after the change. E.g. to run the benchmark:

cd attribute
go test -timeout 60s -run=xxxxxMatchNothingxxxxx -test.benchtime=100ms -count 6  -bench=BenchmarkNewSet | tee results.txt

Then compare using benchstat

benchstat old.txt new.txt

@dashpole Noted, I will share those. Thank you for clarifying this.
