This PR changes the behavior of Lut::get to discard any bits in the input which go beyond the LUT's allocated capacity (via bits_stored), thus making it no longer panic and seamlessly enabling pixeldata to convert 9-bit to 15-bit images filling in the highest bits of pixel data sample values.
add Lut field sample_mask
prevents excluded high bits from being considered in the translation
remove Lut field signed, which is no longer necessary because masking is always applied
