Introduce 'mulaw' voicing_domain and mu-law energy handling across configs and preprocessing. Configs updated to include voicing_domain='mulaw' (acoustic/variance templates and instances). Acoustic/variance binarizers now pass hparams['voicing_domain'] to get_voicing. Parameter adaptor clamps voicing max to 0 when domain is 'mulaw'. get_energy_librosa and get_voicing gain new domain/mu params and implement mu-law compression (default mu=255) to produce a dB-like range compatible with existing pipelines. These changes add support for mu-law representation of voicing/energy. revert
