[Akilon27]

I am submitting

• a new package
• an update for a package

longops :

• the four basic operations now work in bases from 2 to 36
• added option 'arrows' to division to show when digits are pulled down (thanks to Y.D.X. in https://forum.typst.app/t/how-to-draw-a-vertical-line-across-grid-cells/6384) and 'arrows-coef' to adjust the length or the arrows
• renamed parameters to have them all in english (there was a weird mix of french and english ones) breaking change
• added help-en and help-fr to get help in english or french (provided by tidy, like the manuals).

moustaches:

• improvements to gridmath module with better math-grid, and helper functions to use it for matrix...
