message: ENH: relax tolerance for check_fe_interp test
  The `check_fe_interp` test, which tests the FE-based
  interpolation operator in mint, was failing on release
  builds due to strict tolerances being employed. The failure
  was specific on TOSS platforms using the Intel 16 compiler.
  Fixed that.
