Subject: [PATCH] Adding Normalize and Remap functions (#1247)

* Adding Norm and Remap functions

// Normalize input value within input range
// Remap input value within input range to output range

* Rename Norm to Normalize

To make it uniforms with Raylib's functions

* Calculate Remap without other functions
