<muonsocks>: microsocks enhancement package request

[lars18th]

The microsocks package already exists: https://pkgs.staging.openwrt.org/package/master/packages/aarch64_cortex-a76/microsocks

But it only supports Socks v5. For v4a support the we need to use "muonsocks" that it's a fork: https://github.com/niklata/muonsocks

I don't recommend to "replace" the original microsocks package, but to "add" the new one. To compile the fork we can reuse the receipt for the original package.
