Feature request: cache for a quickly load

[eporedieis]

That's a great plugin but every time I open Home Assistant I have to wait 3-4 seconds for the calendar loading: that change element positions in the page layout (when opened, Atomic has an height of 0px, then it changes in the next seconds). I think a cache of the events could solve this problem, then every "xx" minutes/hours/days the plugin could update the list.
Could this be a good solution? Could it be interesting for the future of the plugin?
Thank you very much!
