This changes are made to allow to use some special features relevant for Analogizer: native Zapper Lightgun, Enable/Disable DeJitter timing and use additional clock for video DAC.
At the end I'm forced to change some things in the Analogizer side to leave some logic resources shifting to BRAM when is possible. Also I've shorten the vector width in case sentences to the minimal. the last thing was to remove synchronizer for the interact.json settings, only keep sync the external_reset signal to avoid glitches on this vital signal.
I have further reduced the resources consumed by the Analogizer framework by taking advantage of the fact that the video output is 18bits instead of 24bits. I have also added a TCL script and the Windows Powershell launcher file to generate the different bitstreams from the command line. The PLL used for NTSC/PAL timing is the same (nes_pll) but the clock speed settings are adjusted based on a parameter (USE_PAL_PLL). See the build_and_install_instructions.txt file for more information on this and the generate.tcl script.

Hi, this huge PR contains several commits. Basically, the core is pre-prepared for Analogizer support (enable/disable dejitter, and native Zapper support). Once this is done, Analogizer's own features are added, and the PLL needs to be modified to add a new clock output for Analogizer and the Y/C module. A later commit adds Chip32 support and adds a number of parameters to control which modules are added to the core in the bitstream, this reduction in logic resources per bitstream allows to enable the VRC7 mapper. During this process, it is also necessary to reduce the logical resource consumption to make room for all the necessary functionality. Finally, some corrections need to be made to the Analogizer video YC module, a refactored parameterized PLL module and a script needs to be added to generate output files from the command line with quartus_sh. A final modification was added to interact.json to enable/disable Analogizer globally.
