LZMA
0x5d at the beginning (it's a flag), a 32bit field (size of the dictionary) and the lzma data.
The raw lzma stream usually starts with a 0x00 (offset 0x5)
Note: if you use "comptype lzma_compress" in QuickBMS to compress data, your output will start with 0x2c instead of 0x5d, I modified the dump to make everything easier for you.
