Implement title field for first H1/H2 heading (if no title field exists)

[mdbraber]

I'd like to be able to query the title of a Markdown document being the first H1 or H2 heading in the document. This is described in the comments of the Markdown parser:

obsidian-dataview/src/data-model/markdown.ts

Line 22 in 4829a83

public title?: string;

- but is not (yet?) implemented. Would it be possible to implement this?

For those who want a quick solution, update data-import/markdown-file.ts around line 67 and include

let title: string | undefined;
if (metadata.headings && metadata.headings.length > 0) {
    title = metadata.headings[0].heading;
}

and include title in the returned PageMetadata

@mdbraber do you want to make your change into a Pull-Request?

I would propose to even add the full HeadingCache[] to the Page-Info,
so we can query it for any number of problems.

I think it is more value to provide the full Heading Info as demonstrated here:
master...SpocWeb:obsidian-dataview:headings-in-PageInfo

Don't have time to do it right now; but I'll see if I can get to it later

Try to have a look at my link above, because it covers all Headings. If you would second this, I would make it a PR.

Fine with me!
