This is the context structure for saving the state of data uncompression when LZ77-compressed data is being read from the Card and undergoing streaming uncompression. The context is initialized by the MI_InitUncompContextLZ function and used by the MI_ReadUncompLZ function to save the uncompressed state.
| destp | Pointer to region where uncompressed data will be written |
| destCount | Remaining write size |
| destTmp | For storing data while writing |
| destTmpCnt | For storing data size while writing |
| flags | For storing compression flag data |
| flagIndex | For storing the current index of flag data |
| length | For storing the size of the continuous write |
| lengthFlg | For storing whether offset information spanning 2 bytes is currently being read |
