Some new demos and song uses CIA1/CIA2's timer values and serial shift register as code to execute!
In order to properly debug what is doing on one needs the debugger to _see_ at least some of those values, hence the "if (machine().side_effect_disabled())" on select registers only.
* Unify code for copying PNG data into bitmap for MAME and pngcmp
* Fix upsampling of monochrome PNGs (need to splat across byte)
* Add support for greyscale+alpha
* Detect more unsupported conditions rather than just behaving badly

(nw) This is the path of least resistance, and I plan to fix it up
later, I just wanted to get it to actually work first. Decompression
and unfiltering is fully supported, at least for all the pixel formats
that previously worked. Expanding 1/2/4bpp to 8bpp should work
properly, too. Bitmap mapping for Adam7 is only implemented in
rendutil.cpp which is whate everything in MAME uses. The function in
png.cpp (used by pngcmp) has not been updated. At some point I'll unify
at least one of the functions in rendutil.cpp with the one in png.cpp
and we can go from three functions that need to do the mapping down to
two at the most.
- Correct the decryption of some V25 opcodes used in the EEPROM service routine
- Remove the ugly routine that hardcoded a region for each set
- Add and document a secret input that rewrites the EEPROM for any region
consolidate more logic, more code deduplication, fix gutters on dats
view, fix fallthrough from dats to save
there's some weirdness with shortcust for dats/export/favourite toggle
if they result in a character being typed
