[rust] object pooling #11

inspired by https://www.reddit.com/r/rust/comments/ozpspr/improved_my_base64_encoders_performance_3x_by/,

i tried to re-use the many ObjectEntry objects that get created (and their byte Vec<u8>'s) using a pool.

benchmarks look very promising!

                        time:   [13.003 µs 13.027 µs 13.061 µs]
                        thrpt:  [76.564 Kelem/s 76.761 Kelem/s 76.904 Kelem/s]
                 change:
                        time:   [-39.290% -39.190% -39.087%] (p = 0.00 < 0.05)
                        thrpt:  [+64.169% +64.447% +64.716%]

at the moment is broken, but bench is very promising: ``` time: [14.653 µs 14.666 µs 14.678 µs] thrpt: [68.127 Kelem/s 68.187 Kelem/s 68.245 Kelem/s] change: time: [-32.673% -32.541% -32.415%] (p = 0.00 < 0.05) thrpt: [+47.962% +48.238% +48.529%] Performance has improved. ```
