added decoder errata paragraph
...
for compressed blocks of size exactly 128 KB
which used to be disallowed by the spec
but have become allowed in more recent version of the spec.
While this limitation is fixed in decoders v1.5.4+,
implementers should refrain from generating such block with their custom encoder
as they could be misclassified as corrupted by older decoder versions.

spec update : require minimum nb of literals for 4-streams mode
...
Reported by @shulib :
the specification for 4-streams mode
doesn't work when the amount of literals to compress is 5 bytes.
Extending it, it also doesn't work for sizes 1 or 2.
This patch updates the specification and the implementation
to require a minimum of 6 literals to trigger or accept the 4-streams mode.
The impact is expected to be a no-op :
the 4-streams mode is never triggered for such small quantity of literals anyway,
since it would be wasteful (it costs ~7.3 bytes more than single-stream mode).
An informal lower limit is set at ~256 bytes,
so the technical minimum is very far from this limit.
This is just meant for completeness of the specification.
