* Split hc55516 core into separate cores/subclasses for hc55516 and hc55532 (new 'digital' implementation based on decap/die tracing) as well as mc3417 and mc3418 (old existing 'analog' implementation left alone) and hooked the hc55516 and mc3417 implementations to the appropriate hardware drivers. This should vastly improve CVSD sound quality in drivers that use the hc55516. [Lord Nightmare, Sean Riddle]
* Made Exidy's mouse trap use a timer to clock the mc3417 and update the state readable by the z80 rather than relying on the mc3417 to accept a clock parameter and update the z80 state via a callback. The timer implementation ensures proper synchronization and prevents missed clock transitions from the z80 side causing noise in the CVSD audio. [Lord Nightmare]
* Added a biquad-based 2nd order filter emulation for an audio stream (to go along with flt_rc 1st order filter emulation) and hooked it to Exidy's mouse trap (mc3417) and williams drivers (hc55516) following the original schematics. For hc55516 this is necessary as the original chip produces a very pronounced audible 16khz 'carrier' in its output audio even on the real chip, and these filters suppress this. This also happens to a lesser extent with the 8khz quieting waveform noise on both mc3417 and hc55516. [Lord Nightmare]
* Made Williams System 11 and s11_bg relative sound mixing more accurate to the original audio flow on the PCB itself. [Lord Nightmare]
* Switched Williams Joust 2 to use the s11_bg common sound device rather than its own implementation. [Lord Nightmare]
Fixes: MT #02508
"// according to MT #02508 Stern/Seeburg logos should have different colors."
New color PROM produces title screens that match screenshots from PCBs.
Updated Stern's Super Bagman and now the title also match screenshots from PCBs.
Redumped all ROMs and PROMs so we now have verified correct ROM / PROM labels.
Also improved symmetry of disk components, fixed positioning of
components when fitting to the pixel grid, and fixed inherited color
when item has no color specified.
Removed the dotmatrix components from complay.py - there are more
flexible ways to achieve the same thing.

* fmtowns: add a SCSI card slot for the original models
- Add a slot device for the Model 1/2 dedicated SCSI slot
- Add a device for the FMT-121 SCSI Card
- Modify the I/O maps and machine configurations so the slot and the
integrated controller don't overlap
Moved MS DIB parser out of ICO file reader and made it available for
artwork and layout images.
Added more efficient I/O and better error checking for JPEG file loading
(MAME will no longer exit immediately on a bad JPEG file).
Made caller responsible for opening files for loading images, to avoid
decompressing images used in ZIP/7z artwork multiple times.
Added support for JPEG and Windows DIB to picture_image_device.
Added support for SVG image files in external artwork.
Added support for using I/O port value for animation state and masking
animation state values.
Made bounds elements more flexible in layouts.
Reworked headers to reduce dependencies.
Updated layout file format documentation.
