[Suggestion] Option to only take into account 'postcontent'

[ChipsPbx]

Hi,

It would be great if we could have the option to choose which actual progress the bar displays, between "All the page" (header, content, footer etc...) and "Only content".

If the plugin works wonders on desktop, on responsive mobile it can be misleading because the length of the page can be artificially longer. If for example on mobile your sidebar is displayed after the post content, then the progress bar takes that sidebar into account. Meaning the reader has finished reading the actual content, and yet the progress bar is still at 50 or X%, because of what is still below on the page.

It would be cool to be able to choose what the readers actually read :)

Hi,

I have created a pull request for solving this issue: #3

So that if the DOM contains a <main> tag, this will be the reference item for progress, else it uses the whole document as the current case.
