Issue while building manual

[TanguyBarthelemy]

I got an error while building the manual of rjd3filters

> devtools::build_manual()
Error in `value[[3L]]()`:
! Failed to build manual
Run `rlang::last_trace()` to see where the error occurred.

This doesn't give us much information so I ran the command line:

Error in running tools::texi2pdf()

The error is due to the symmetric moving average matrix which does not fit on a single line:

Maybe displaying the equation on a new line or changing the size of the characters?

Thanks, this come from the fact that by default matrix cannot have more than 10 columns and thus it breaks it into 2 lines. I updated the formula to define it with the backward operator instead of the matrix notation.
