User https://listenbrainz.org/user/Kanau/ recently reported that their page doesn't load. It does, but it takes 52 seconds to load. The user has a one page of listens spread over 3 years, so timescale needs to scan back a ways to load the data for the user.

To address this we, should do the following things:

1. Render the front-end page without data and give the user visual feedback as we load the listens
2. Create a new API endpoint to fetch listens based on a timestamps only, without offset/count. Then deprecate the old API endpoint and immediately start using the new endpoint for LB.
3. Load up to say, a month, of data on the page and if we don't load 25 listens, show a button to load more listens, warning user that this could take a while.
