Add trigonometric filter operators (#6127)
* Added missing trigonometrics filter operators

This PR adds support to trigonometry operators, allowing to create spider graphs and other geometric shapes with filters.

* Adds the missing trigonometric filter operators

This PR adds support to the missing trigonometric filter operators (cos, sin, tan, acos, asin, atan, atan2), allowing to create spider graphs, [pie charts, donut charts, polar charts](https://ffoodd.github.io/chaarts/pie-charts.html) and other geometric shapes with filters, which was previously not possible without add-ons.

Example :

`[[2]cos[]] = -0.4161468365471424`
