[1.16.5 Compat bug] Using Controllable to grab a ledge causes "wriggling" and cannot be followed up by a jump

**Summary**
Issue is in the title. The "wriggling" animation is the torso of the player's model animating rapidly because of the spammed input

**Running Environment**
+ Minecraft Version: 1.16.5
+ ParCool Version: 2.1.0.0-R
+ Forge Version (optional): 36.2.39

**Detail**
This issue is arising because controllable spams inputs that are held, rather than having an available held state to read from. Consider implementing a custom flag check instead of relying on the input classes isHeld method.

More than likely affects all available versions
