[Enhancement][Evernote] Allow importing HTML features not supported by markdown

[AltoRetrato]

I'd like to suggest that the Obsidian importer ask users whether they want unsupported Markdown features to be imported as HTML tags.

I'm not sure if this issue is specific to Evernote, but I've noticed that many formatting features are lost when importing notes into Obsidian, such as:

• Underlined text
• Superscript
• Subscript
• Specific color highlight
• Font size, type and color
• Special table formatting, e.g., merged cells

Below is a screenshot comparing a note in Evernote before and after importing it into Obsidian:

Since Obsidian supports both Markdown and HTML, it's capable of rendering these features with HTML tags, for example:

<u>Underlined text</u>,
<sup>Superscript</sup>,
<sub>Subscript</sub>,
<span style="background-color: lightblue;">specific color highlight</span>,
<span style="font-family: Georgia, serif; font-size: 16px; color: #A00000">font size, type and color</span>

Here's a screenshot of Obsidian rendering the HTML above:
