	Auto link a string.

	Options:

	* `class: "auto-linker"` - specify the class to be added to the generated link. false to clear
	* `rel: "noopener noreferrer"` - override the rel attribute. false to clear
	* `new_window: true` - set to false to remove `target='_blank'` attribute
	* `scheme: false` - Set to true to link urls with schema `http://google`
	* `truncate: false` - Set to a number to truncate urls longer then the number. Truncated urls will end in `..`
	* `strip_prefix: true` - Strip the scheme prefix
	* `exclude_class: false` - Set to a class name when you don't want urls auto linked in the html of the give class
	* `exclude_id: false` - Set to an element id when you don't want urls auto linked in the html of the give element
	* `exclude_patterns: ["```"]` - Don't link anything between the the pattern
	* `markdown: false` - link markdown style links
	* `email: false` - link email links
	* `mention: false` - link @mentions (when `true`, requires `mention_prefix` or `mention_handler` options to be set)
	* `mention_prefix: nil` - a prefix to build a link for a mention (example: `https://example.com/user/`)
	* `mention_handler: nil` - a custom handler to validate and formart a mention
	* `hashtag: false` - link #hashtags (when `true`, requires `hashtag_prefix` or `hashtag_handler` options to be set)
	* `hashtag_prefix: nil` - a prefix to build a link for a hashtag (example: `https://example.com/tag/`)
	* `hashtag_handler: nil` - a custom handler to validate and formart a hashtag
	* `extra: false` - link urls with rarely used schemes (magnet, ipfs, irc, etc.)

	Each of the above options can be specified when calling `link(text, opts)`
	or can be set in the `:auto_linker`'s configuration. For example:

	config :auto_linker,
	class: false,
	new_window: false

	Note that passing opts to `link/2` will override the configuration settings.
