Subject: Add frequency number handlebars (#600)

* Add frequencies-num handlebar

* Fix handlebar name

* Fix inconsistent variable name format

* Add frequency-number to anki tests

* Use full names for total and frequency variables

* Migrate handlebars to JS, split rank and occurance, add average

* Remove left behind frequency-number

* Fix "occurrence" spelling

* Cleanup types

* Add frequency support for kanji cards

* Fix code style

* Clean up most of duplicate code and merge functions

* Fix frequencies.length check

* Use less witchcraft and remove redundant type casting
