    [CARBONDATA-1756] Improve Boolean data compress rate by changing RLE to SNNAPY algorithm

    Improve Boolean data compress rate by changing RLE to SNNAPY algorithm
    Because Boolean data compress rate that uses RLE algorithm is lower than SNNAPY algorithm
in most scenario.
    
    We also add some test case for testing  Boolean data compress rate.
