[IMP] Charts: add calendar chart

[anhe-odoo]

Task Description

This task aims to add the possibility to analyze temporal records by grouping the value associated to each date into time periods (e.g. year, date, month, hour of day, ...). This analysis is added as a new chart which could be further adapted if we want to make heat map based on a matrix data.
