Resolve #742: "Wrongly formatted header"

• Related issues: #742 (closed)
• Requested reviewers:

Reason why this change is needed

The file-header for the following files is not formatted corrected (i.e. whitespace at the beginning of the lines has been removed):

• lib_dec/ivas_mcmasa_dec.c
• lib_rend/ivas_dirac_rend.c
• lib_rend/ivas_masa_merge.c

This should be fixed - otherwise it makes automatic patching of these headers unnecessarily difficult.

Description of the change

Add whitespace to copyright header line beginnings of the mentioned files to match the rest of the framework.

Affected operating points

• The change affects only comments in the code, not the executable code.
• Produced bitstream and output are BE.
