If parentsha1 != 0, we have a parent (no need for flags)
If compressors[0] == 0, we are uncompressed (including maps)

V5 uncompressed map format:

[ 0] uint32_t offset; // starting offset / hunk size
[ 0] uint32_t_t offset; // starting offset / hunk size

V5 compressed map format header:

[ 0] uint32_t length; // length of compressed map

[ 4] UINT48 datastart; // offset of first block

Each compressed map entry, once expanded, looks like:
