Browse Source 
* gguf_dump.py: fix markddown kv array print

* Update gguf-py/scripts/gguf_dump.py

Co-authored-by: compilade <git@compilade.net>

* gguf_dump.py: refactor kv array string handling

* gguf_dump.py: escape backticks inside of strings

* gguf_dump.py: inline code markdown escape handler added

>>> escape_markdown_inline_code("hello world")
'`hello world`'
>>> escape_markdown_inline_code("hello ` world")
'``hello ` world``'

* gguf_dump.py: handle edge case about backticks on start or end of a string
