Theme objects can be either a Map or object where the keys are the selectors
and the values are either a styling function or an array of styling
functions to be applied in order.
The _ style rule applies to the block as a whole, and is used
as the default style. This is where you'd usually port a PrismJS
theme's code[class*="language-"] css rule.
The lineNumber style rule will apply to line numbers, if they
are used.
The semantics are similar to CSS, where a nested property will be
applied to nodes within that nesting stack with a higher
priority the more tags that match, and later rules taking
precedence over earlier ones. It's not a full CSS selector
syntax though, so things like .token.italic.bold aren't
supported. Just individual token class names, possibly nested.
Also, chalk is not CSS, and a terminal is not a browser, so
there are some differences and limitations of course.
Aliases are also not supported, styles have to be applied to the
actual parsed class names PrismJS provides.
