Fetches script/language-specific font extents. These values are
looked up in the BASE table's MinMax records.
If no such extents are found, the default extents for the font are
fetched. As such, the return value of this function can for the
most part be ignored. Note that the per-script/language extents
do not have a line-gap value, and the line-gap is set to zero in
that case.

This function is like harfbuzz.global.otLayoutGetFontExtents but takes #hb_script_t and #hb_language_t instead of OpenType #hb_tag_t.
