firmware/scroll: Update credits to include forgotten contributors

[ghost]

What about those real people, whose labor was used in the creation of ZX-Uno and of scroll demo in particular? Let's see:

• In 2016 you used FuenteABin tool which uses sources of the project LodePNG, developed since 2005 by Lode Vandevenne. This tool is used to convert PNG image fuente6x8.png into a binary fuente6x8.bin file used to show all of those credits on the screen in the scroll demo. But unfortunately there is no mention of him in that list of contributors. In the current state of the scroll demo without his work we could not even see any authors and contributors on the screen as like as the demo itself (no intermediate binary file - no final result);
• The team of SJAsmPlus Z80 compiler. Widely used across the project;
• The team of Xilinx, Inc.. Ross Freeman (co-founder of Xilinx, Inc.) has invented the field-programmable gate array (FPGA), which is the heart of ZX-Uno now.

I think we should pay respect to the work of these people (at least at the time of creating this demo). Will it be fair to mention them in the credits?

Something like this will be fine, I think:

The team of LodePNG project
The team of SJAsmPlus project
The team of Xilinx, Inc.

Ok. I agree to mention all these people. Go ahead

By the way should I add or you will add to the credits? I assigned you for this issue but I'm unclear who should add them. (And I've missed the team of Sinclair Research Ltd from view - parents of ZX Spectrum itself)

You can add them to the credits

I opened an issue https://github.com/zxdos/zxuno/issues/81 to find missing sources of the binary file needed to modify the credits. I can move on after closing that issue.
