Too many decimals for CPU speed in GHz

In my case I can see `CPU: AMD Ryzen 7 3700X (16) @ 4.426171 GHz` in `fastfetch` [v2.1.0](https://github.com/fastfetch-cli/fastfetch/releases/tag/2.1.0) output which seems rather overly specific, could there be a config option / default to 2 similar to `--size-ndigits`?

I can reproduce this under both glibc Void and musl Chimera Linux.
