Libhydrogen bindings for Erlang

## About

helium provides Erlang bindings to the Hydrogen Crypto Library ([libhydrogen](https://www.libhydrogen.org/doc/)).

Working with helium is simple in both Erlang and Elixr.

- ***Erlang***
```erlang
1> N = helium:rand(42).
<<115,97,120,157,28,208,118,165,137,95,122,152,195,49,52,
  188,73,136,216,201,77,183,29,144>>
1> helium:rand(42).
<<196,216,103,100,59,248,220,7,212,176,11,59,76,54,33,27,
  87,166,157,249,120,120,106,253,233,234,148,136,133,...>>
```

- ***Elixir***
```elixir
iex(1)> n = :helium.rand(42)
<<115,97,120,157,28,208,118,165,137,95,122,152,195,49,52,
  188,73,136,216,201,77,183,29,144,110,108,111,101,180...>>
```
