.color method is slow

# Expected Behavior

I would expect some simple colour manipulation to not take longer than 2 seconds.

# Current Behavior

Currently it takes about 8 seconds.

## Steps to Reproduce

```typescript
console.time("process time");

// Tested with any 1600x900 image
const imageBuffer = await image
.color([
{ apply: "desaturate", params: [90] },
{ apply: "darken", params: [40] },
])
.contrast(0.3)
.getBase64Async(Jimp.AUTO);

console.timeEnd("process time"); // process time: 7.738s
```
```
No options: process time: 228.178ms
Only contrast: process time: 232.918ms
Only desaturate: process time: 4.191s
Only darken: process time: 4.153s
```
