Bug description

Edit one of the points on the fan curve and enter anything non-numerical. For example 55C. Press enter. LACT will immediately crash. Entering a non-integer value like 55.1 also acts a bit strange. Although these should just be rounded to the nearest value.

System info

- LACT version: 0.5.4
- GPU model: ASrock Taichi 6800XT
