Implement a linear-interpolation math node that maps an input value
from an input range [in_min, in_max] onto an output range
[out_min, out_max].
- node.py: SimpleLERP class (classic INPUT_TYPES/RETURN_TYPES pattern),
float inputs for value and both ranges, plus a clamp toggle. Guards
against a zero-width input range and supports inverted ranges.
- __init__.py: export NODE_CLASS_MAPPINGS / NODE_DISPLAY_NAME_MAPPINGS
for ComfyUI discovery.
- README.md: usage, formula, and inputs/outputs tables.
