Fix arg of drawAngerMark background color type

[u-tanick]

src/Effect.h

bColor of drawAngerMark is set to uint32_t.
Please correct it to uint16_t.

  void drawAngerMark(M5Canvas *spi, uint32_t x, uint32_t y, uint32_t r,
                     uint16_t color, uint32_t bColor) {
    drawAngerMark(spi, x, y, r, color, bColor, 0);
  }

  void drawAngerMark(M5Canvas *spi, uint32_t x, uint32_t y, uint32_t r,
                     uint16_t color, uint32_t bColor, float offset) {
    r = r + abs(r * 0.4 * offset);
    spi->fillRect(x - (r / 3), y - r, (r * 2) / 3, r * 2, color);
    spi->fillRect(x - r, y - (r / 3), r * 2, (r * 2) / 3, color);
    spi->fillRect(x - (r / 3) + 2, y - r, ((r * 2) / 3) - 4, r * 2, bColor);
    spi->fillRect(x - r, y - (r / 3) + 2, r * 2, ((r * 2) / 3) - 4, bColor);
  }
