Free DSP coefficient table v0.2.1

Sys/GC/dsp_coef.bin and SysPlayback/GC/dsp_coef.bin are generated filter coefficients from the
free DSP ROM project, licensed under GPL-2.0-or-later. They are not a console ROM dump.

The table is 4096 bytes. SHA-256:

The generator produces 128 phases of four Q15 taps for three cutoffs, using Hamming and Kaiser
windowed sinc filters, followed by 1024 zero bytes. A player's own console coefficient dump in
User/GC/dsp_coef.bin takes priority. That player-supplied file is never copied into a release.
The applicable GPL text is supplied as COPYING.txt in this folder; the combined program is
distributed under GPL-3.0-or-later.
