Linear Levels

# This Mod been folded into the [Train's Tweaks](https://modrinth.com/mod/trains_tweaks) mod under the Experience feature for 1.21+. LinearLevels adds ~~three~~ five configuration options for how you want the experience "curve" to work in your game. These configuration options can be found in [ModMenu](https://modrinth.com/mod/modmenu) or similar mods. Requires [Cloth Config API](https://modrinth.com/mod/cloth-config). By default, every level will take 10 experience points (compared to vanilla this feels quite low so I recommend configuring it to your liking). Alternatively, you can enable Curve Mode, which uses the formula (XPToNextLevel = (baseXPForOneLevel + (experienceLevel * curveModeMultiplier)). I find Curve Mode's defaults to be my preference, as the curve doesn't get ridiculous after level 30 like in vanilla. (yes, the name Linear Levels isn't accurate in this case, I know) For the exact numbers of both modes and their comparisons to vanilla on a graph, see this [Google Sheet](https://docs.google.com/spreadsheets/d/1odNYoPElp61PSQIwmVLbh3zHttry5cQYojXIBB8U7w4/edit?usp=sharing). 1.1.0 adds an additional config option: Level Cap. It's disabled by default, but by setting a value, the experience required for the next level will stop increasing at the specified level. **FAQ**: *How will this work with XP storage mods*? It depends on how those mods work. In other words, I don't know. The only thing this mod does is mixin to one method in the player entity.
