I have a .cue file which points to a .flac 

How can I mount the image as if it were an audio CD? Is it necessary to decode the .flac file into .wav and edit the cue sheet to point to a .wav file instead (it currently points to the flac)?

I want to use `abcde` to split, tag, and encode the audio. 

Answers I've found on here already discuss .cue/.bin combo, not audio images..
