Debugging checklist

• [x] Have you read the troubleshooting page (https://montreal-forced-aligner.readthedocs.io/en/latest/user_guide/troubleshooting.html) and searched the documentation to ensure that your issue is not addressed there?
• [x] Have you updated to latest MFA version (check https://montreal-forced-aligner.readthedocs.io/en/latest/changelog/changelog_3.0.html)? What is the output of mfa version?
• [x] Have you tried rerunning the command with the --clean flag?

Describe the issue When running the CLI, passing in --beam and --retry-beam are not parsed as valid options and are instead passed as arguments.

> mfa align_one --beam=400 --retry_beam=1000 -t /mfa_data -j 4 --clean --use_threading --use_postgres --single_speaker /mfa_data/my_corpus/recordedNames.wav /mfa_data/my_corpus/recordedNames.txt english_mfa english_mfa /mfa_data/my_corpus_aligned/recordedNames.TextGrid

 Usage: mfa align_one [OPTIONS] SOUND_FILE_PATH TEXT_FILE_PATH DICTIONARY_PATH ACOUSTIC_MODEL_PATH OUTPUT_PATH

Ahh this is only an issue if the flags are the the beginning. Moving the flags to after the positional arguments fixed it.
