wrpll.ddmtd: fix first edge deglitcher
...
The blind counter should be held in reset whenever the input is high,
not just when there is a rising edge (otherwise the counter runs down
during the main pulse and can then re-trigger on jitter from the falling edge)

wrpll.filters: the helper clipping threshold is currently way too low. Move clipping after the bitshift to increase a bit.
