Long notes are a huge part of mania gameplay, especially with all the o2jam-style maps out there. But finding LN-heavy maps is kind of a pain since beatmap tags are often missing or wrong, and some players just want to avoid LNs entirely.

The another rhythm game Quaver has this neat LN percentage filter, so I figured why not add it to osu!mania too? Now you can filter maps by how much of them are actually long notes.

What's new

• Added ln/lns keywords to search - works with all the usual operators (=, !=, >=, >, <=, <)
• Uses percentages (0-100) because that's way more intuitive than decimals
• Examples:
  • ln=0 - maps with no long notes
  • ln>=50 - maps with 50% or more long notes
  • ln<10 - maps with less than 10% long notes
• Added tests

Known Issues

This might not work perfectly on converted beatmaps since I'm using EndTimeObjectCount instead of actually parsing the HitObjects from the Beatmap class. But honestly, if you're hunting for LN maps you're probably not looking at converts anyway, so it should be fine for what people actually want to do.
