146  offCode等于====== common function ======
148  如果staticPrices则返回:ZSTD_getLiteralPrice(seqStorePtr, litLength, literals)加====== common function ======加16加offCode
151  price等于offCode加log2offCodeSum减====== common function ======
152  如果非ultra且offCode大于等于20则price加等于offCode减19的差乘2
157  ML_deltaCode等于36
158  mlCode等于如果matchLength大于127则====== common function ======加ML_deltaCode否则ML_Code[matchLength]
159  price加等于ML_bits[mlCode]加log2matchLengthSum减====== common function ======
162  返回:price加ZSTD_getLiteralPrice(seqStorePtr, litLength, literals)加factor
