New features for TOC

[foxton9]

Glad to know new toc was released.

As in #103, I'd like to focus solely on adding features rather than the TOC widget itself.

New features for the existing toc

1. active headings indicator
2. synchronization with page scrolling

I think the implementation needs further discussion, as I'm not fully satisfied with the current solution.

It seems there will be some updates for the TOC on mobile and its styling, so I haven't tested those cases.

Thanks a lot for your contribution!
The features are great, but there are still some issues.

The logic of isPageReady may need to be revised:

• When clicking on a post at the top of the page, the active headings are not set initially since there's no scroll to trigger the scrollend event. When using the mouse wheel, the event won't be fired until the user stops scrolling for the first time.
• On top of that, if the post is short enough, some headings might never be marked as active because they never leave or enter the viewport.
