feat(commands): Add convenient names for read-data-subset n/m

[aawsome]

This PR adds convenience names for the -read-data-subset=n/m option which allow for more easy regular check runs which cover the whole repository data over a given period.

E.g. it allows to daily run check --read-data --read-data-subset=daily/month which covers the repository once run at every day of any month. Before, this requirement needed scripting to set n to the number of the current day within the month and m to the total count of days in the current month.

For n, it is now allowed to use

• hourly
• daily
• weekly
• monthly
• yearly
  which is replaced by an index corresponding to the date/time the check command is called.

For m, it is now allowed to use

• day
• week
• month
• year
  which is depending on n replaced by the total count of hours/days/weeks/months within the current entity. Moreover month_hours, month_days, year_hours, year_days which work independent from n.
