erofs-utils: support limit max decompressed extent size
Currently, some data pattern (e.g. zeroed data) could cause very
high CR with EROFS. However, for such extreme high C/R compressed
pclusters, the kernel side hasn't optimized such cases yet (such
as decompressing such pclusters fully in advance.)
Alternatively, let's add support to limit each decompressed extent
size for now.
