3rd party asset exporter tool for NEXXT

Riemann on the NESdev discord, aka Eigenvector32 on github just published this:
https://github.com/eigenvector32/nexxtporter

It's a command line tool for extracting .chr, .nam and .pal files as you please from a NEXXT session (.nss). It can also generate .png bitmaps.

Putting this in your build instructions, you can make sure your NES project always has up to date assets from your working NEXXT sessions. This can allow for better version control than exporting assets manually from within NEXXTs GUI
