HID: elecom: add support for ELECOM HUGE 019B variant

The ELECOM M-HT1DRBK trackball has an additional device ID (056E:019B)
not yet recognized by the driver, despite using the same report
descriptor as earlier variants. This patch adds the new ID and applies
the same fixups, enabling all 8 buttons to function properly.
