Given two hashes like this 

HGB: { result: 2.1, observed_at: "2017-12-12 00:01:01",
CRE: { result: 9, observed_at: "2017-12-12 00:01:01"}

} {

HGB: { result: 1.0, observed_at: "2018-12-12 00:01:01"}, # changed
CRE: { result: 1.1, observed_at: "2017-12-11 00:01:01"}, # no change!
PTH: { result: 1.1, observed_at: "2017-12-11 00:01:01"}  # new!

} Return a hash that looks like this {

 HGB: [
   { result: 2.1, observed_at: "2017-12-12 00:01:01"}, # original
   { result: 1.0, observed_at: "2018-12-12 00:01:01"}, # changed
   -1.1 # digg

 CRE: [
   { result: 9, observed_at: "2017-12-12 00:01:01"},
   nil, # no new value

 PTH: [
   nil, # no original
