Option to disable remote fonts

[gkrishnaks]

Is your feature request related to a problem? Please describe.
Feature request to add an option to disable remote fonts. Ublock Origin browser addon provides this option.

Describe the solution you'd like
In "Content Control" page, a new setting switch that's by default OFF, to allow user to disable remote fonts.

I took a quick look into the code and noticed that in this class/fn, looks like the code already has the ability to detect if a sub-resource request is of type font.

fulguris/adblock/AbpBlocker.kt
in shouldBlock fn, request.type is already ContentRequest.TYPE_FONT for a font sub-resource request.

Describe alternatives you've considered
Content Control page in Fulguris does not already provide this option. Internally, Fulguris is already able to determine if a sub-resource request is a font type.
