Summary

This branch makes several housekeeping changes to release wpa version v1.8.0. The main changes since the previous version are:

• the realignment of workpatterns_classify() to improve its consistency (see Refactor: improvements on workingpatterns_classify_bw()  #215).
• the adding of the external_* family of plotting functions which visualise the metric Collaboration_hours_external (See Feature: New 'external collaboration' family of functions #223).

Changes

The changes made in this PR are:

1. Removed stray HTML file in the repository root.
2. Added missing documentation for arguments for plot_hourly_pat().
3. Increment version to v1.8.0 and submit to CRAN.
4. Add Viva Insights OData link repo to README.md
5. Added the function identify_date_freq() that partially addresses Feature request: distinguish Date frequency in extract_date_range() #131. This is not completely fixed as this has not bee incorporated into extract_date_range().
6. Use pad2() in scenarios where a two-digit zero-padded value needs to be created.

Checks

• All R CMD checks pass
• roxygen2::roxygenise() has been run prior to merging to ensure that .Rd and NAMESPACE files are up to date.
• NEWS.md has been updated.

Notes

This addresses but does not fix #131.
