Breakdown of IMSI into MCC, MNC and MSIN

[punisherVX]

Need to break down IMSI into its sub-parts of
MCC - 3 digits
MNC - 2 digits
MISN - gte 10 digits

Doing this at ingest time, with logstash, will allow for building visualizations without having to stress elasticsearch with regex and painless scripting which are both search intensive.
