Various improvements (see PR)

[rpeyron]

Hello,

Thanks for your plugin that was very useful to me for my Jekyll migration from WordPress.

I have made some customizations that may interest some other users:

• added comments export, with three destination possible:
  • as data / collections (to be treated with some liquid)
  • as posts with metadata and markdown as contents
  • as GitHub discussions for use with Giscus
• added Polylang plugin extraction of languages (and reference to translated pages, and unifying translated categories and tags)
• added some processing to WordPress contents:
  • remove the site host add by WordPress to get relative URI (useful to test on other hosts before switching)
  • improved code section conversion, specially when using WordPress plugin crayon
  • export image alignment in markdown styles
  • convert spoiler tag to details HTML tag
• added some metadata and filtered useless ones from oceanwp WordPress theme (list is configurable)
• and various settings to execute the script outside WordPress folders, to skip some parts of the script (useful to speed-up when running multiple times with posts or script modifications), and to generate without zip in a specific folder

Hope these little things can be useful

Thanks again for the plugin,

Thanks for the pull request! I like a lot of the intended functionality here and believe it could be useful to others if generalized for other setups. I've left some comments in-line.

If you'd like to see this PR forward, I'd also want to see tests added for any new functionality and it looks like PHPCS is throwing some style errors since I activated CI on this PR.

Hello, thanks for your feedback. I have fixed and answered your remarks above.

About tests, do you have some in mind to start with? I certainly won't have time and skills to implement all.
About PHPCS, do you know a linter/formatter for VSCode? Also, it is throwing 700 errors, that is more than the number of line modified, this is crazy!
