[PD] [iir] doesn't handle nan, -inf, inf and very small numbers well

Pix and I are here working in AVLAB using [iir] for filtering data
from [wiimote]. It turns out that [iir] gets stuck at inf or -inf if
it receives one. This makes sense in a math sense, but not in a Pd/
practical sense.
We are thinking that [iir] should filter out -inf, inf, and perhaps
nan as well. Seems like they would be useful objects for other
things too. Something like:
- filter nan [no_nan]
- filter inf/-inf [no_inf]

expect we're going to win that war. We're not going to win the war
on terrorism. - retired U.S. Army general, William Odom
