warning: undefining the allocator of T_DATA class FileMagic

[Lykos]

I recently updated from Ruby 3.0.2 to 3.3.0 and I started getting the following warning at the line where I call FileMatic.new:

warning: undefining the allocator of T_DATA class FileMagic

I googled it but didn't find anything useful about this error message. Good luck!

I just found out that #46 seems to fix this.

I am also encountering this same issue and for #46 it seems there is still some open question whether it is a proper solution. Would be good to see a fix of this.

@blackwinter is there any chances you merge this MR?
