Vague error when no height or width tag is in the svg

[oskeith]

When exporting an svg from Adobe Illustrator, by default, "responsive" is ticked and no width or height tag is set. In that case, a vague error is thrown. I think it would really help a new user if there was a check and an appropriate message if the svg has no width or height tag.

import svgutils.compose as sc
sc.SVG(os.path.join(file_directory, 'face_border resp.svg'))

File "[main]", line 55, in
sc.SVG(os.path.join(file_directory, 'face_border resp.svg'))
File "C:\Users\keith\miniconda3\lib\site-packages\svgutils\compose.py", line 122, in init
if svg.width.endswith("%"):
AttributeError: 'NoneType' object has no attribute 'endswith'

Thanks!

Same with some SVGs I have to deal with, even after editing manually in Inkscape.

Sample affected file:

zip of file for easier download maybe:
test.zip

Resizing canvas of the svg in Inkscape fixes this by the way.
