Consider adding more formatting options for color generators

Consider adding more formatting options for color generators.

Note
CSS Colors Level 4 no longer requires commas in CSS color functions, and implements a slash syntax for alpha channels: rgba(123, 45, 67, .8) in old is equivalent to rgb(123 45 67 / .8) in new.

New color functions introduced by Level 4, hwb, lch and lab, only support the new syntax. Of these, as of writing, only hwb has widespread support in browsers.

Possible settings changes

• Add a setting option for which generators to include in menus, so that not all of them are listed all the time (not sure if this is possible?)
• Add a setting to toggle including alpha channel values
• Remove CSS compliant format setting (superceded by selectable format options)

Possible formats
