YDS slash grades broken

[musoke]

I expect that 5.10a/b should convert to a score range that is a subset of those for 5.10a and 5.10b. It is actually the same range as for 5.10a.

This test should pass:

    test('slash grades should be subset', () => {
        const slashScore = YosemiteDecimal.getScore('5.10a/b')
        console.log("slashScore = ", slashScore)
        const lowScore = YosemiteDecimal.getScore('5.10a')
        console.log("lowScore = ", lowScore)
        const highScore = YosemiteDecimal.getScore('5.10b')
        console.log("highScore = ", highScore)

        expect(slashScore[0]).toBeGreaterThan(lowScore[0])
        expect(slashScore[1]).toBeGreaterThan(lowScore[1])
        expect(slashScore[0]).toBeLessThan(highScore[0])
        expect(slashScore[1]).toBeLessThan(highScore[1])
    })

actual output:

  ● Console

    console.log
      slashScore =  [ 57, 61 ]

  ● YosemiteDecimal › slash grades › slash grades should be subset

    expect(received).toBeGreaterThan(expected)
