feat: Add additional scale inputs (Y and Z axes) for Condition effects

[arran4]

Implemented additional scales for Y and Z axes in the Condition effects setup. Modified the main.cpp UI code to add sliders for Axis Y (column 2) and Axis Z (column 3). Also modified ffb.cpp to populate all three axes for SDL_HapticEffect.condition array elements from the values in effect_data. Also added .gitignore to ignore the ffdstudio binary.

• Update main.cpp UI to show right_sat, left_sat, right_coeff, left_coeff, deadband, and center sliders for Axis Y (_1) and Axis Z (_2).
• Update ffb.cpp to populate SDL_HapticEffect.condition parameters for all 3 axes from the UI values instead of just the X axis.
• Added .gitignore for the ffdstudio compiled binary.

Fixes #2
