    gnu: openfst: Add 1.7.3 for kaldi
    
    Kaldi is currently broken with openfst versions newer than 1.7.3 as it 
changed
    some of its function signatures.
    
    Once Kaldi is patched/fixed, this should be removed.
    
    Reference Issues:

    - https://github.com/kaldi-asr/kaldi/issues/4393
    
    * gnu/packages/machine-learning.scm (openfst-1.7.3): New variable.
