ColorPicker is really limited as an element

[Kira-Kitsune]

It would be nice to have more features within ColorPicker as it does feels really limited at the moment, many other UI libraries have a way more detailed/useful color picker and would love to see PrimeVue to have a better one.

Some suggestions of features:

• Alpha Slider (toggle)
• Position of Slider(s) (left, right, bottom, top)
• Input for colour (format for each colour format) within the popup/inline (also positional)
• More colour formats (CMYK, HSL, etc.)
• Able to have an "outside" text field or better integration into InputText
