Zeroing the DAS weight for out-of-bounds reads is not enough: the lerp still loads x[offs0], which is an illegal memory access when planewave offsets are not clipped to the IQ buffer. Skip the load unless the sample index is in bounds.

Closes #2.
das_alg1_kernelnow skips the IQ lerp/load when the computed sample index is out of bounds, instead of relying on a zero weight after the load.
