Feature Request: Add option to set backgroundColor in light mode and dark mode separately.

qwerzl

Hi there, first of all, thank you for your work! It would be nice if it's possible to set the background color separately like as following: ``` const options = { bottom: '64px', // default: '32px' right: 'unset', // default: '32px' left: '32px', // default: 'unset' time: '0.5s', // default: '0.3s' mixColor: '#fff', // default: '#fff' backgroundColorDark: '#fff', // default: '#fff' backgroundColorLight: '#000', buttonColorDark: '#100f2c', // default: '#100f2c' buttonColorLight: '#fff', // default: '#fff' saveInCookies: false, // default: true, label: '🌓', // default: '' autoMatchOsTheme: true // default: true } ``` In my specific case, I would like my website to be `#000` in light mode, but when the darkmode is applied, the color `#FFF` is far too dark. It really affects the reading experience.

You can set backgroundColor to whatever you want. When darkmode is off then you should remove custom background: `document.getElementsByClassName('darkmode-background')[0].remove();`
