compression does not work well

func Test_gorilla(t *testing.T) {
	var buf bytes.Buffer
	c, finish, err := gorilla.NewCompressor(&buf, 27550378*60)
	assert.NoError(t, err)

	for i := 27550378; i < 27550388; i++ {
		t.Log("write: ", uint32(i*60), float64(i))
		assert.NoError(t, c.Compress(uint32(i*60), float64(i)))
	}
	assert.NoError(t, finish())

	d, _, err := gorilla.NewDecompressor(bytes.NewReader(buf.Bytes()))
	assert.NoError(t, err)

	itr := d.Iterator()
	for itr.Next() {
		fmt.Println(itr.At())
	}
}

the output is

fix function compressValue

	leadingZeros := uint8(bits.LeadingZeros64(xor))
	trailingZeros := uint8(bits.TrailingZeros64(xor))

	if leadingZeros >= 32 {
		leadingZeros = 31
	}
        if c.leadingZeros != ^uint8(0) && c.leadingZeros <= leadingZeros && c.trailingZeros <= trailingZeros {
                // do something
        }
