Feature: add function for anonymizing data

[martinctc]

Summary

This branch introduces a function for anonymizing data, as per #156. The use case of this function is to make POC artifacts shareable, as they are often created using real Workplace Analytics data which is typically highly confidential.

Changes

The changes made in this PR are:

1. Added anonymize() / anonymise().
2. Added jitter_metrics()

Examples

Anonymize the Organization attribute:

sq_data %>%
  mutate(Organization = anonymise(Organization)) %>%
  email_sum(hrvar = "Organization")

Add jitter to a metric:

jittered <- jitter_metrics(sq_data, cols = "Collaboration_hours")
head(
  data.frame(
    original = sq_data$Collaboration_hours,
    jittered = jittered$Collaboration_hours
  )
)

  original jittered
1 18.74210 18.73427
2 15.02403 15.00658
3 14.27897 14.29141
4 12.69034 12.68973
