stocksCRPS and factorsSPGMI sectors misspelled and not official GICS naming conventions used

factorsSPGMI and stocksCRSP do not use official GICS naming conventions in sector names. In addition, several securities have obvious misspellings in Sector assignment, resulting in incorrect groupings. For example:

`unique(factorsSPGMI$Sector) # contains 16 sectors with dupes`

` [1] "InfoTech" "Industrials" "HealthCare"
[4] "ConsumStap" "Energy" "Materials"
[7] "ConsumDisc" "TelcoServices" "Utilities"
[10] "RealEstate" "Health Care" "Financials"
[13] "Consumer Discretionay" "Information Technology" "Consumer Staple"
[16] "Communication Services"`

For those 16 "Sectors" above, the following mapping would be correct:

| Sector (in factorsSPGMI) | Official GICS Sector Name |
|:-------------------------|:--------------------------|
| InfoTech | Information Technology |
| Industrials | Industrials |
| HealthCare | Health Care |
| ConsumStap | Consumer Staples |
| Energy | Energy |
| Materials | Materials |
| ConsumDisc | Consumer Discretionary |
| TelcoServices | Communication Services |
| Utilities | Utilities |
| RealEstate | Real Estate |
| Health Care | Health Care |
| Financials | Financials |
| Consumer Discretionay | Consumer Discretionary |
| Information Technology | Information Technology |
| Consumer Staple | Consumer Staples |
| Communication Services | Communication Services |
