Define silver measure with reference to names in dm+d

Since the ODD changes, several branded presentations no longer have
"silver" in their name.  Instead, we can find branded presentations by
looking up AMPs whose VMP has "silver" in the name.  This new method
finds several other matching presentations that weren't initially
included, increasing the value of the numerator by about 20% over all
practices in 2019_12.
