neomutt: Add html-email creation pipeline to compose menu

Browse source 
Hitting `,m` in the compose menu creates a dual txt/html email group
when the highlighted file is written in (djot) markdown.

Delete the original message afterwards to create a fully functional html
email with plaintext fallback.

Completely taken from: https://tom.wemyss.net/posts/neomutt-markdown-email/
with many thanks. What an amazing use of pipelines in neomutt!
