[Feature request] Analysis - suggestion to include Focus Keyword in Post's Title

Please give us a description of what happened.

There is no warning when not including the Focus Keyword in the post's title (not the SEO Title).

The Analysis meta field does not check if the Focus Keyword is in the post title (which implies being in an H1 tag).

In my test, the post's title is completely irrelevant to the focus keyword:

As long as the SEO Title includes the Focus Keyword, I do not receive any warnings about including the Focus Keyword in the Post's Title / an H1 tag.

Please describe what you expected to happen and why.

I expected a red bullet telling me to include the focus keyword in the Post's Title too (which should be an H1 on most themes)

How can we reproduce this behavior?

1. Create a post with a random Post Title
2. Select a Focus Keyword
3. Include Focus Keyword in SEO Title, but not in the Post Title
