What kind of file type do you need? Searching on google isn’t giving me a clear answer but I’m happy to help if I can. If it’s more complicated than converting to a file type I might not be able to do it, I just made these on an art programme that allows saving as .cur files and I have very little programming experience. It’s not that I ‘won’t’ make them, I would love to make them as available as possible, it’s just that I don’t know how and from what you have said I suspect it may be beyond my ability, sorry T_T - that being said, the .cur image files are freely available to be edited and manipulated however you like for personal use. I know some people use browser extensions to use them just when surfing the web, a more limited use but this could be an option for you.
