UCL NRV2d decompressor for PDP-11

NRV2d decompression algorithm implementation for PDP-11 compatible microprocessor.

IMPORTANT. This code does not accept original packed byte sequences's final marker. The compression subroutine ucl_nrv_99_compress must be modificated to emit short final code prefix:
UCL version: 1.03, file src\n2_99.ch, line #605, original:

code_prefix_ss12(c, UCL_UINT32_C(0x1000000));

Should be:

code_prefix_ss12(c, UCL_UINT32_C(0x100));

You can use n2dpack utility in bin folder to create packed streams.
