摘要：ZSTD_loadEntropy() :

1876  dictPtr等于 must point at beginning of a valid zstd dictionary
1877  dictEnd等于dictPtr加dictSize
1879  如果dictSize小于等于8则返回:-***************************************** Error codes handling(dictionary_corrupted)
1881  dictPtr加等于8
1884  hSize等于HUF_readDTableX4_wksp(hufTable, dictPtr, dictEnd - dictPtr, workspace, workspace的长度)
1885  如果HUF_isError(hSize)则返回:-***************************************** Error codes handling(dictionary_corrupted)
1887  dictPtr加等于hSize
1892  offcodeMaxValue等于MaxOff
1893  offcodeHeaderSize等于-*************************************************************** FSE NCount encoding-decoding
1894  如果=== Error Management ===则返回:-***************************************** Error codes handling(dictionary_corrupted)
1896  如果offcodeLog大于OffFSELog则返回:-***************************************** Error codes handling(dictionary_corrupted)
1899  dictPtr加等于offcodeHeaderSize
1904  matchlengthMaxValue等于MaxML
1905  matchlengthHeaderSize等于-*************************************************************** FSE NCount encoding-decoding
1906  如果=== Error Management ===则返回:-***************************************** Error codes handling(dictionary_corrupted)
1908  如果matchlengthLog大于MLFSELog则返回:-***************************************** Error codes handling(dictionary_corrupted)
1911  dictPtr加等于matchlengthHeaderSize
1916  litlengthMaxValue等于MaxLL
1917  litlengthHeaderSize等于-*************************************************************** FSE NCount encoding-decoding
1918  如果=== Error Management ===则返回:-***************************************** Error codes handling(dictionary_corrupted)
1920  如果litlengthLog大于LLFSELog则返回:-***************************************** Error codes handling(dictionary_corrupted)
1923  dictPtr加等于litlengthHeaderSize
1926  如果dictPtr加12大于dictEnd则返回:-***************************************** Error codes handling(dictionary_corrupted)
1930  dictContentSize等于dictEnd减dictPtr加12
1931  以i小于3循环
1932  rep等于ZSTD_readLE32(dictPtr)
1933  dictPtr加等于4
1934  如果rep恒等于0或rep大于等于dictContentSize则返回:-***************************************** Error codes handling(dictionary_corrupted)
1936  rep[i]等于rep
1940  返回:dictPtr减 must point at beginning of a valid zstd dictionary
