[AU-221865] Balance - good diggers will incur higher stress

It's the only job that by-design requires you in ugly locations - and the better your dupe is at digging the more they hate it.  Stopping digging to place decor isn't that fun.  What I've found I need to do is rotate jobs between digging and those that can be done in a constrained location (such as cooking).  For 1-2 dupes this is ok but beyond that it's more micro than I like.

Few approaches I can see:

• Leave it as it is - it's a dirty job, this is a way of saying 'I did my time'
• Dupes really love digging - while actually digging give them a "doing a job I love" bonus to offset the stress incurred from drab surroundings
• Create a natural alternate use for digging that can take place in nicer surroundings 
• ???  Y'all are more creative than I am
