Doc/readme-updates

Hey there @masasam,

While revisiting the package and Hugo documentation to find a way to implement featured post images, I came up with some README modifications listed at the end.

Rather than introducing an images field into the org template, as we did for categories in #73, which was a good default, I wrote a brief explanation on how to include custom front matter fields/keywords for easy-hugo-org-header users, based on Front Matter docs. I think this approach makes more sense this time since the images field wouldn't be a sane default for the template, due its narrow use case and its dissonance from other templates fields in the repo.

The easy-hugo-list-draft is working fine with the easy-hugo-org-header set, so I removed a statement on that. Optionally, I also did some changes in the intro of the README, centering the logo and restructuring the synopsis---not sure if these were desired, so feel free to edit or drop them completely.

TLDR:

• added a front matter howto to easy-hugo-org-header users
• removed a false positive feature absence/conflict
• introduced some changes to the readme intro (at your discretion)

(My very first PR on GitHub was on this repo and you kindly welcomed it even though I was a newcomer. That encouraged me to learn more and contribute to open-source projects that I use. So thank you for your time and dedication to this package. I was happy to see it featured in the Hugo documentation.)

Well, not sure if I like the logo centered anymore hahaha ¯_(ツ)_/¯

(Let me know and I revert it if you want)
