Currently enabling readability checks only, others to follow. Of the
four disabled readability checks, three (function-cognitive-complexity,
identifier-length, magic-numbers) require extensive refactoring and were
left for later, and one (redundant-access-specifiers) is not planned to
be fixed due to the current coding style - using extra sections to
separate methods from variables of the same visibility.
