Feature request: Support link reference definitions.

[NfNitLoop]

Instead of creating all links inline, it would help the readability of unrendered Markdown documents if there were an option to move all links to link reference definitions at the end of the document.

Ex:

Here is some text with a [link](https://0bin.net/paste/s735Z5wG#IFueVOPicYrnyDjhxp7NlMcFGG7N6WjYwyz9Lsgdubr) that can become distracting in the middle if plaintext. Especially if there are [multiple](https://www.google.com/) [links](https://www.wikipedia.org/) [close](https://github.com) to each other.

Would be much nicer to read as:

Here is some text with a [link] that can become distracting in the middle if plaintext. Especially if there are [multiple] [links] [close] to each other.

[link]: https://0bin.net/paste/s735Z5wG#IFueVOPicYrnyDjhxp7NlMcFGG7N6WjYwyz9Lsgdubr
[multiple]: https://www.google.com/
[links]: https://www.wikipedia.org/
[close]:  https://github.com

Or even with explicit link references like this, if that's easier to automate:

Here is some text with a [link][1] that can become distracting in the middle if plaintext. Especially if there are [multiple][2] [links][3] [close][4] to each other.

[2]: https://www.google.com/
[3]: https://www.wikipedia.org/
[4]: https://github.com

This is a feature I really like in https://pypi.org/project/html2text/, and I see mentioned in https://github.com/mixmark-io/turndown

Great suggestion! Added to my queue.

Thanks! Looking forward to trying this out! 👍 (Though that’ll probably be when the link space issue is fixed, since that’s a blocker for me.)

Added in v1 via useLinkReferenceDefinitions option.

@NfNitLoop Sure thing. Working on that.

Finally got around to using this. Works great, thanks!
