update rustler to 0.24

[ayrat555]

use NewBinary instead of OwnedBinary (https://github.com/rusterlium/rustler/blob/master/CHANGELOG.md#0240---2021-02-24)

I did some benchmarks

with NewBinary

Operating System: macOS
CPU Information: Intel(R) Core(TM) i5-1038NG7 CPU @ 2.00GHz
Number of Available Cores: 8
Available memory: 16 GB
Elixir 1.12.1
Erlang 24.0.1

Benchmark suite executing with the following configuration:
warmup: 2 s
time: 1.67 min
memory time: 1.67 min
parallel: 4
inputs: none specified
Estimated total run time: 3.37 min

Benchmarking ex_keccak...

with OwnedBinary

ex_keccak       51.55 K       19.40 μs   ±650.83%          20 μs          54 μs

Memory usage statistics:

it seems with NewBinary the library performs better both in terms of memory and ips

Awesome, thanks @ayrat555!
