Yantramanav incorrectly declares U+0000-00FF support

I am using the Yantramanav font for a project and noticed that fractions such as ½ ¼ are not supported. However, when checking the `@font-face` declaration, a `unicode-range` of `U+0000-00FF` is provided, which prevents the browser from falling back to a system font with fraction support.

Removing the `U+0000-00FF` range from the `unicode-range` property fixes my problem. I would like to submit a PR for this; however, I am not sure if removing this will also remove other glyphs in this range which are supported.
