Wrong stick coordinates since Slippi 2.5.0

[CollaboratingElephant]

Device: Leonardo R3 Arduino ATMega32U4 Pro Micro
Host: USB-B to USB-A, DIYGCC_USB
Game: Melee, Slippi 2.5.0
Buttons pressed while plugging in: None
Actions: Pressing modX and various control stick directions

Expected behaviour:
Modx+down producing the Y value of -0,28750,
Modx+left producing the X value of -0,66250
Modx+left+down producing the X value of -0,73750, and Y value of -0,28750

Actual behaviour:
Modx+down produces the Y value of -0,27500
Modx+left produces the X value of -0,65000
Modx+left+down produces the X value of -0,72500, and Y value of -0,27500.

All of this started happening only when Slippi updated to 2.5.0, and Arte suggested it might be because of this pull:

The Slippi team reverted the changes that lead to the issue. Problem solved.
