Fetches the raw MathKern (cut-in) data for the specified font, glyph index,
and kern. The corresponding list of kern values and correction heights is
returned as a list of HarfBuzz.ot_math_kern_entry_t structs.
For a glyph with n defined kern values (where n > 0), there are only
n−1 defined correction heights, as each correction height defines a boundary
past which the next kern value should be selected. Therefore, only the
HarfBuzz.ot_math_kern_entry_t.kern_value of the uppermost HarfBuzz.ot_math_kern_entry_t
actually comes from the font; its corresponding
HarfBuzz.ot_math_kern_entry_t.max_correction_height is always set to
INT32_MAX.
