You could use firgr
A FIR filter for decimation is just like any other FIR filter but you only need to calculate the output samples you need, that is every nth sample for a decimation factor of n. You can have multiple stop bands with firgr. You specify the stop bands to cover the bands of frequencies that will alias into your wanted band after decimation. You can allow the response to rise at frequencies that don't alias into your band.
