c610a01d7d fix #3719 
only disable `--rm` at end of command line parsing,
so that `-c` only disables `--rm` if it's effectively selected,
and not if it's overriden by a later `-o FILE` command.

eb5f7a7fa2 produced golden sample for the offset==0 decoder test 
is correctly detected as corrupted by new version,
and is accepted (changed into offset==1) by older version.

updated documentation accordingly, with an hexadecimal representation.

a9fb8d4c41 new method to deal with offset==0 
in this new method, when an `offset==0` is detected,
it's converted into (size_t)(-1), instead of 1.

The logic is that (size_t)(-1) is effectively an extremely large positive number,
which will not pass the offset distance test at next stage (`execSequence()`).
Checked the source code, and offset is always checked (as it should),
using a formula which is not vulnerable to arithmetic overflow:
```
RETURN_ERROR_IF(sequence.offset > (size_t)(oLitEnd - virtualStart),
```

The benefit is that such a case (offset==0) is always detected as corrupted data
as opposed to relying on the checksum to detect the error.

2abe8d63e0 fix LLU->ULL 
LLU is a correct prefix according to C99 & C11 standards (but not C90).
However, older versions of Visual Studio do not work with it.
Replace by ULL, which doesn't have this issue.

8d31e8ec42 sizeBlockSequences() also tracks uncompressed size 
and only defines a sub-block boundary when
it believes that it is compressible.

It's effectively an optimization,
avoiding a compression cycle to reach the same conclusion.
