Summary: lpreson~ crashes if not properly initialized

Initial Comment:
[lpreson~] is very likely to crash.
e.g.: start Pd with lpreson~ loaded, create a new [lpreson~] object, turn-audio on: crash!

this is because the filter coefficents do not exist yet, but is accessed in the dsp routine.

the attached file fixes this, and also moves the t_atom->float conversion code into the list-callback (which will supposedly be called less often than the perform routine).

finally, the patch uses "t_sample" rather than "t_float" and/or "float", to allow this object to work in Pd-doubleprecision builds as well.
