example improvements

[JeromeSchmied]

• fix(examples/html2term): more (vim-alike) keybinds
• fix(examples/html2text): use yansi instead of termion for colouring
  • adds support for hyperlinks
  • more intuitive IMO
  • less dependencies

And here I thought Termion was low-dependency...
Thanks for the changes! I've made a few comments.

[jugglerchris]

Should remove the termion dependency if it's no longer used.

[jugglerchris]

I don't think the hyperlinks should be on by default, but fine with an opt in option (--hyperlinks or similar).

[jugglerchris]

You can't add extra visible text here - the colour map function is not expected to change the size of any text, or it would mess up the formatting. As above, the hyperlink should only be done with an option to enable it.

[jugglerchris]

The text should already be struck out already by this point (using U+336).

[JeromeSchmied]

Note

one test doesn't pass, as I've removed the unicode character strikethrough thing

should I revert it and use the old method, or use the new one (yansi .strike()) which IMO looks better, but only applies in the html2text example, not elsewhere, and delete the test?

I've got the following question: is there a fairly easy way of turning markdown-like decorations in the scope of examples/html2text? I find it quite annoying, that *bold text looks like this* and would prefer bold text to look like this without the *-s

Hi. About the strikeout, I think it should at least be an option, since terminal escape sequences aren't always available.

There are a couple of options:

1. Use --literal (under the hood uses TrivialDecorator)
2. Use --colour (possibly with --css and the css feature enabled), which uses internally uses the "Rich" output which adds metadata annotations instead of textual decoration, and adds some terminal colouring.
