more refactor and add encode/decode steps to benchmark

mengdilin commented 2 months ago

Summary:

previously, there is 1 benchmark that measures the reconstruction error and then measures the performance of the distance computation for the scalar quantizer. Split it up into distance benchmark and accuracy benchmark.
add performance benchmarks for encode and decode as well
refactor the benchmarks to accept n and d as command line arguments. We run the benchmarks with n = 2000 and d = 128 to start. Happy to expand it to d=256 and a higher n if we think it's better.
refactor the targets file so we can create servicelab experiments based on different parameters

Planning to use the benchmarks here to test my simd refactor changes (and expand the benchmarks when necessary).
