Should error if output name does not match input name

[jphickey]

Is your feature request related to a problem? Please describe.
The cFE build scripts assume that the file name of the output of elf2cfetbl matches the input basename but with a .tbl extension added.

In reality, this tool uses the output name specified in the source file. If this doesn't match, an obscure installation error occurs because the "expected" binary file will be missing.

Describe the solution you'd like
elf2cfetbl should error out if the input name does not match the output name.

Describe alternatives you've considered
Alternatively, the tool could have a new command line option added to directly control the output name and override whatever was in the source file. This would be a more substantial change, however.

Additional context
This can create confusion when the multiple table feature in nasa/cFE#1538 is used. If the source file internal definition doesn't match the expected name the error occurs later at install time, not when elf2cfetbl runs, so it can be confusing.
