Cannot set selector to ignoreIfFocusOn option

[fugudesign]

Hi!
First, thanks for this very usefull lib and for the time saved !

I detected an issue:

The type defined in the code is ignoreIfFocusOn?: boolean;, but the doc says :

For example, if you set this option to 'input', scan events will not be fired if an input field is focused. You can either pass an DOMElement, a CSS selector or an array containing multiple besaid objects.

So, it's currently impossible to set a selector with Typescript.

Could it be possible to fix this issue?
