Fix infinite binary output when processing .ts files with no subtitles

[tusharbhatt7]

Problem
When CCExtractor processes a .ts file that contains no subtitles, it produces infinite binary/hex-like output in the terminal instead of stopping gracefully.

Solution
Removed the dump() call in copy_capbuf_demux_data() for CCX_PRIVATE_MPEG2_CC buffer type. This dump was using CCX_DMT_GENERIC_NOTICES which is enabled by default, causing continuous binary output to the terminal.

Changes

• Removed dump(CCX_DMT_GENERIC_NOTICES, ...) call from copy_capbuf_demux_data() function
• Added explanatory comment about why the dump was removed
• Function still processes data correctly, just without the debug output

Testing

• Verified that the problematic dump call is removed
• Code still handles CCX_PRIVATE_MPEG2_CC buffer type correctly
• No infinite binary output when processing TS files with no subtitles

Fixes #1754

It seems that not all tests were passed completely. This is an indication that the output of some files is not as expected (but might be according to you).
