Allow to reset the INP calculation

Hi,

it would be awesome if the package would offer a resetINP function or something similar.

Use case We would need this feature as we take a look at the "subpages" of SPAs as individual pages and would be highly interested in the individual INP values of them. Because of the way the entries are collected in longestInteractionList this of course is not really possible.

Possible Solution I guess clearing prevInteractionCount, prevInteractionCount, longestInteractionMap in this new reset function should be enough? Or do I miss something here?

Value This clear function would allow for more different use cases (in combination with the already present reportAllChanges: true) while increasing the complexity and package size only slightly. I think this is a valuable addition! Thanks!
