S-YXG2026 Hybrid instrument definition for QWS

Copy inst_syxg2026_hybrid.ini beside qws.exe, then select S-YXG2026 Hybrid
from QWS's instrument-list control. The definition contains 1,309 unique
programs across 80 banks and uses QWS's combined bank value: MSB multiplied
by 128, plus LSB.

SG singing names are included for reference, but SG songs also require their
original setup SysEx; selecting an SG name alone does not create that setup.
