About resvg from its documentation:
> resvg is an SVG rendering library. The core idea is to make a fast, small, portable SVG library with the goal to support the whole SVG spec.

## Installation

The package can be installed
by adding `resvg_nif` to your list of dependencies in `mix.exs`:

```elixir

end
```

## Usage

```elixir
:ok = Resvg.svg_to_png("input.svg", "output.png")

svg_string = """
<svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke-width="1.5" stroke="currentColor">
  <path stroke-linecap="round" stroke-linejoin="round" d="M2.25 15a4.5 4.5 0 004.5 4.5H18a3.75 3.75 0 001.332-7.257 3 3 0 00-3.758-3.848 5.25 5.25 0 00-10.233 2.33A4.502 4.502 0 002.25 15z" />
