Implementation of the new Equitherm algorithm (#146)
* feat: new equitherm algorithm and chart for it (#144) * refactor: refactoring after #144 * refactor: cosmetic changes (equitherm chart) * chore: fix typo * refactor: cosmetic changes * chore: remove unused files * chore: resolve conflicts * refactor: added notes for equitherm parameters * fix: decimation for Equitherm chart fixed; chartjs updated * style: HTML code formatting * chore: added additional description of the ``T`` parameter for Equitherm * flx: typo * refactor: after merge --------- Co-authored-by: P43YM <ip43ym@gmail.com>
