Parses link headers

## Installation

1. Add the dependency to your `shard.yml`:

   ```yaml

   dependencies:

     link-header:

       github: spider-gazelle/link-header

   ```

2. Run `shards install`

## Usage

```crystal

require "http/client"

require "link-header"

# Parse the links out of the response

response = HTTP::Client.get "http://www.example.com"

links = LinkHeader.new(response)

# equivalent to the above

links = LinkHeader.new(response.headers)

# Get the first link matching a `rel`

links["next"] # => "https://next.link/"  or raise KeyError

links["next"]? # => "https://next.link/" or nil

# Get all the links matching a `rel`

links.get("preconnect") # => ["https://link.1/", "https://link.2/"]

links.get("missing") # => []

```
