Markdown references in headings such as '####' don't render well. Replaced it with <h4>...<a></a></h> banners.
The backend should only be initialized once, otherwise it is reloaded. Added `init_backend` function, intializes a backend attribute. Phonemize re-uses self.backend. Should give ~10 times faster phonemization.

What does this PR do?
This is my FIRST PR!
The Wav2Vec2PhonemCTCTokenizer is slow when its argument
do_phonemizeis set to True. It re-initialises the backend at each forward pass. This is adressed using a class argument.There was also an H4 title in the documentation which had a link which did not render(
<h4></h4>used to replace####)Tests were passed, no additional ones were created. Runtime experiments to phonemize the entire 'tr' (turkish) subset of the common voice dataset gives a x10 boost in performances.
