Adobe Font Metrics

/**
parseCharMetrics() takes a single line from the "CharMetrics" section in an
AFM file, and extracts the crucial metrics for that character. For example, the
line describing capital A in Times-Roman from Adobe's Core14 font set is this:

    C 65 ; WX 722 ; N A ; B 15 0 706 674 ;

For which parseCharMetrics() would return a plain object:

    { charCode: 65, width: 722, name: 'A' }

From https://partners.adobe.com/public/developer/en/font/5004.AFM_Spec.pdf:

> `C integer`: Decimal value of default character code (−1 if not encoded).
> `CH` hex`:   Same as C, but the character code is given in hexadecimal.
               Either C or CH is required
> `WX number`: Width of character.
> `N name`:    (Optional.) PostScript language character name.
