1. Add benchmark performance in README.md
2. Use an Attr as argument for New to initiate a cache, in this
way, more default settings can be supported.
3. Add fast way for delete method, if no onEvicted callback
function set.
4. Use bool to indicate k existence in Get method to avoid
pointer escape (which leads to memory allocation on heap),
reference link below to get detail information.
