Classnames starting with number cause syntax error

[m0rtalis]

Classnames starting with a number [0-9] cause a syntax error in the generated .css.d.ts file.

An example is the classname 35 00px in SemanticUI which results in the type definition export const 35: string;, which obviously throws syntax errors.

A fix is to change the allWordsRegexp to /^[a-zA-Z]\w*$/i. Although no idea if that's the best approach.

Interesting.. because css officially doesn't allow digits as the first character of a class name.

Yes apparently they have efforts to change the class name Semantic-Org/Semantic-UI#5468 but in the meanwhile can the regex be changed to support such class names?
If yes I can create a PR for this
