Bug in `Pack_Time` (fsw/src/sbn_pack.c): Use of uninitialized variable

[Nodraak]

Hi,

Bug: in https://github.com/nasa/SBN/blob/main/fsw/src/sbn_pack.c#L55, D is uninitialized and packed into PackPtr

Solution: the return value from OS_TimeAssembleFromMicroseconds() should be assigned to D.

Root cause: this change introduced the bug.

This bug was found with CPPcheck: Line 24: Uninitialized variable: DataBuf

This has been solved in the internal version. We'll push the solution when it's published.
