Error when svg file contains references to font with space in its name

[nyq]

When input SVG file refers to a font with a space in its name (e.g. "Cascadia Code"), calling svg2rlg results in Unable to find a suitable font for 'font-family:Cascadia Code', weight:normal, style:normal warning messages and the default font is used instead.

Specifically, what happens is that when the font name has a space in its name, convertFontFamily method of Svg2RlgAttributeConverter class located in svglib.py splits the input font name into multiple strings using space character as a delimiter (line 406), and then feeds these split strings into find_font method of FontMap class located in fonts.py, resulting in all calls to find_font failing (because it gets "Cascadia" and "Code" as separate inputs during two separate calls).

There are plenty of fonts with a space character in their name, even in standard Windows distribution, so using space character as a separator is not warranted and breaks the functionality.
