Dwell Table instantiated on stack, but not used

Describe the bug
During init, the MD app instantiates a dwell table on the stack, and memset's it to 0:

MD/fsw/src/md_app.c

Line 331 in b0ae64d

MD_DwellTableLoad_t InitMemDwellTable;

However this is not anywhere for any purpose. It may be a remnant that was never cleaned up.

As a result, its using several kB of stack space unnecessarily.

Expected behavior
Should not allocate objects that are not necessary.

System observed on:
Debian

Additional context
This was discovered by analyzing the stack usage and finding that MD sometimes overran its allocated stack. Although there were other issues as well (see nasa/osal#1429) ... it was noted that this unneeded object was a significant contributor for why the problem showed up in MD and not other apps.
