Request: Modify Norn price feeds

Hey,

Can you please alter the price feeds for the Norns (Skuld, Verthandi & Urthr) to use the following new values?

CER: 0.95 (Up from 0.8)
MCR: 105 (Down from 200)
MSSR: 101 (Down from 110)

The intent behind this change is to encourage more participation. I believe these values will work due to the constrained volatility within the Norns ABA feed.

The black swan recovery method will soon also be changing from the default global settlement mechanism, to type 3 where individual undercollateralized positions are converted into market orders; the intent with this is to further encourage market participation.

As the asset owner, I could change these directly however reaching out seemed appropriate. If this route is easier for you and not something you disagree with, then I could go that route with the MCR & MSSR change if you want?

Cheers

edit: Updated the reference price feeds to reflect the change BTS-CM/Norns@5ee6fa7
