Public release of fdump (Version 0.0.6.5)

The version is 0.0.6.5 This version introduces the following:
* allow -k switch to copy files that are zero bytes in length
* allow full free form commandline handling of switch clustering for
-t{o} and -k{y}; e.g., -to|-ot and -yk|-ky are all valid
* fixed bug in -k switch if - (STDIN) was specified; this is invalid
* Provider a cleaner and faster mechanism for write DMA allocation/
deallocation internal handling
* added a file extension construct -i; that is, growing a file past
its last offset with a default octet value of zero if none was
specified
* added a new display mode `clx' that is used in dumping entire files
to STDOUT in a classic Hex editor display look
These are the new features added to version 0.0.6.5
over the prior release 0.0.6.4
