Syntax highlighting - support input to change styling

[owilliams320]

Feature Request

Add ability to switch/change theme of Covalent syntax highlight component programmatically. Currently while trying to use the syntax highlighting component there is not a way to easily set or change the current color schemes programmatically with Angular.

What is the motivation / use case for changing the behavior?

This would help in theming cases where a User would switch to dark or light theme and would like see syntax highlighting matching that currently active theme

Which version of Angular and Material, and which browser and OS does this issue affect?

Angular 9.0

You can overwrite the theming if you switch to dark-mode in your theme setup css file, eg:

// normal theme stuff

@include covalent-highlight-theme();

.dark-theme {
    @import '~highlight.js/styles/vs.css';
}

Example would be to support light / dark highlighting without changing the overall theme
