[BUG] GlyphModder will not override the metadata tags when the tags already exist

[SebiAi]

Describe the bug
When writing to an audio file, which was already written to before, the metadata tags get not updated and remain unchanged.

To Reproduce
Steps to reproduce the behavior:

1. Write the glypha and glyphc1 files to a blank audio file
2. Modify the glypha/glyphc1 files
3. Write them again to the same audio file used in step 1
4. The metadata did not change

Expected behavior
The metadata gets overwritten.

Desktop (please complete the following information):

• OS: Windows, maybe others

Additional context
Output of the GlyphModder on Windows:

python GlyphModder.py -t "LetYouDown" -w labels.glypha labels.glyphc1 LetYouDOwn.ogg
INFO: Auto detected Phone (2) mode.
INFO: ffmpeg command is longer than 32764 characters which is the limit on Windows. Saving metadata to file and passing it to ffmpeg.
Wrote 34964 bytes of AUTHOR metadata
Wrote 466 bytes of CUSTOM1 metadata

Important is that the external file workaround for the metadata was used.

Workarround
You can use this ffmpeg command to strip the audio of ALL its metadata tags:

ffmpeg -i audio.ogg -map_metadata -1 -c:a copy -fflags +bitexact -flags:v +bitexact -flags:a +bitexact audio_clean.ogg

Now pass audio_clean.ogg to the GlyphModder script instead of audio.ogg.

"Bypassed" by making a blank ogg file and writing the files on it, pretty weird and never happened to me before.
