Add font-color control on Fab Group Labels

Is your feature request related to a problem? Please describe. Fab Group label colours can’t be manually changed outside of the theme, and users of a light theme have the label text opacity set to 0.54.

Describe the solution you’d like I’d like to be able to have greater control over fab group label font-color by passing a color in to the styles property and having it affect the label color.

Describe alternatives you’ve considered I’m currently passing in a modified theme in order to achieve a similar result, setting it to a dark theme to avoid the opacity change and setting the font-color to the one I desire.

<Fab.Group
    theme={{
        ...myTheme,
        dark: true,
        colors: {
            ...myTheme.colors,
            text: '#000'
        }
    }}

Additional context There’s a stale pull request removing the opacity change, but I figure that the forced opacity must be there for a reason. I’m happy to make a pull request to allow the user to pass in the font-color themselves. Otherwise it takes the existing theme’s text color and keeps the opacity adjustment.

This is a bit hacky but you can change the label text color by passing this into FAB.Group:

theme={{ colors: { text: 'black' }, dark: true }}

This is because it determines labelColor specifically from the passed in theme.

Dark needs to be true, else it will be 50% opacity.

I really do wish there were options to customize the label though, because I’d like to have the option to make it bigger and add padding. The icon/action styling is useless because props like marginBottom stretches the label along with it
