Strange IndexError caused by [SMACK]

[roedoejet]

I can't provide steps to re-create this because the data is private, but while aligning a specific audio file, an IndexError is thrown when trying to get the word element:

File "/Users/pinea/.pyenv/versions/3.9.14/lib/python3.9/site-packages/readalongs/align.py", line 1006, in get_word_texts_and_sentences
    word_el = get_word_element(tokenized_xml, word["id"])
  File "/Users/pinea/.pyenv/versions/3.9.14/lib/python3.9/site-packages/readalongs/align.py", line 972, in get_word_element
    return xml.xpath(f'//w[@id="{el_id}"]')[0]
IndexError: list index out of range

A breakpoint showed that the word in question was {'id': '[SMACK]', 'start': 74.19, 'end': 75.66} - removing it fixes the issue, but I presume this is something coming from SoundSwallower. @dhdaines - how should we be handling this?

Ah, we should be filtering those noise words out, but for whatever reason we currently aren't. No need to see the private data to fix this, I can make a PR tonight.
