Benchmark

Benchmarks on each commit: https://telecss.github.io/telecss/dev/bench/

This benchmark is based on parsing/tokenizing the crates/telecss/examples/normalizecss/normalize.css file, and the time-consuming of parsing includes the time-consuming of tokenizing:

• Pure Parsing Time = Parsing Time - Tokenizing Time

TODO
