feat(Core): introduce StatusBaseText component

Abstract text component that defaults to Status' `Inter` font.
Also known as `StyledText` in Status Desktop.

This will close #20 as it doesn't make sense to implement multiple
components for a single text type. Size and weight of text can be configured
on a per usage basis.

Closes #20
