Duplicate dimension name error when introspecting druid

[l15k4]

Hey,

we have several dimensions like d_a & d_A or d_key & d_Key which is considered duplicate and Swiv errors out, would it be possible to filter out the duplicates and log error instead of crashing?

Fatal settings load error: duplicate dimension name 'd_a' found in data cube: 'gwiq-daily-p'

I don't know swiv much, so I cannot really tell why it is trying to avoid duplicate dimensions and metrics and as I've never used JS or TS, I'd have hard times to submit a fix.
