GitHub Flavored Markdown extensions

[haimag]

Could add the following GitHub Flavored Markdown extension:

• Add support for Obsidian Flavored Markdown syntax, such as ==Highlighted text== and Internal Links (Wikilinks). Reference link: https://obsidian.md/help/obsidian-flavored-markdown

• SumatraPDF already renders mermaid fences as diagrams. Could it support the display of wavedrom in md? The wavedrom repository: https://github.com/wavedrom/wavedrom

Highlight and wikilinks are in: 6b11219e1

==highlighted text== renders as a highlight. It can wrap other inline markup (==**bold**==) and it is left alone inside code.

[[Page]] links to Page.md next to the current file. [[Page#Heading]] and [[#Heading]] use the same heading anchors as the rest of the markdown view. [[Page|alias]] shows the alias. A missing file stays a link; Sumatra does not create a note.

![[embeds]] and block references ([[Note#^block]]) stay as text. WaveDrom is still open: the library parses the fence with eval, and this view's content security policy does not allow that.
