Unpack abbreviations during evaluation

[saattrupdan]

When evaluating ASR models, we should unpack all common abbreviations from both the ground truth and the model's output, to avoid unfair measurement.

This includes (at least) the following:

• "fx" = "fx" = "f.eks." -> for eksempel
• "bl.a." -> blandt andet
• "m.fl." -> med flere
• "m.m." -> med mere
• "dvs." = "d.v.s." -> det vil sige
• "etc." -> et cetera
• "osv." = "o.s.v." -> og så videre
• "vha." = "v.h.a." -> ved hjælp af
• "ekskl." -> eksklusiv
• "jf." -> jævnfør
• "m.h.p." = "mhp." -> med henblik på
• "mfl." = "m.fl." -> med flere
• "mv." = "m.v." -> med videre
• "mao." = "m.a.o." -> med andre ord
• "ifm." = "i.f.m." -> i forbindelse med
• "ca." -> cirka
• "e.l." = "el." -> eller lignende

We should be careful not to mistakenly replace instances of these when they're not abbreviations, however - they need to be separated by word boundaries at least.
