Reorder second-order sections of biquadratic filter System object

`reorder(`

independently reorders the scale values of the biquadratic filter System object. If `sysobj`

,`numorder`

,`denorder`

,`svorder`

)`svorder`

is not specified, the scale values of
the biquadratic filter are reordered in the same way as the numerator. The output
scale value always remains at the end and `numorder`

is used to
reorder the scale values.

`reorder(`

reorders `sysobj`

,`filter_type`

)`sysobj`

in a way suitable for the specified filter
type. This mode is intended for fixed-point implementations where the ordering of
the sections can have a significant impact on the filter performance.

`reorder(___,'Arithmetic',`

assumes that the filter arithmetic is equal to
`arithType`

)`arithType`

.
