Can be used to figure out the file type and format.

Inspired heavily by [format_parser](https://github.com/WeTransfer/format_parser/).

## Basic usage

```elixir
# Image
{:ok, file} = File.read("myimage.jpg")
match = FormatParser.parse(file)
match.nature        #=> :image
match.format        #=> :jpg

# Video
{:ok, file} = File.read("myvideo.flv")
match = FormatParser.parse(file)
match.nature        #=> :video
match.format        #=> :flv

# Document
{:ok, file} = File.read("mydocument.rtf")
match = FormatParser.parse(file)
match.nature        #=> :document
match.format        #=> :rtf

# Audio
{:ok, file} = File.read("myaudio.wav")
match = FormatParser.parse(file)
match.nature        #=> :audio
match.format        #=> :wav

# Font
{:ok, file} = File.read("myfont.ttf")
match = FormatParser.parse(file)
match.nature        #=> :font
match.format        #=> :ttf

```
