Lucas CHOLLET cd2bf5ebc7 LibGfx/CCITT: Detect and reject contextually-invalid modes ...

Sometime, due to external factor a valid mode can't be applied. As an
example a L2, where b1 - a0 < 0 (variable names are from the spec) is
invalid.

This bug was found by oss-fuzz. Note that the codestream in the issue
is also invalid for other reasons it might prevent the reproduction of
this specific issue (without hacking the code).
