Learning from Nushell and make Arturo better

[scifx]

I discovered Nushell, along with the experimental modules I mentioned earlier, stdin,startup preloading scripts, comprehensive and flexible date calculations, UTF-8 support, cross-platform compatibility, and support for AArch64(I can use it on my phone)—all of which are available in Nushell. It fully meets the requirements I previously mentioned in the issue. I think we can learn a lot from it, though its drawbacks include a relatively large installation size, a bit slow,and unclear documentation. Nonetheless, it definitely serves as an excellent reference!

Date calculations at Nushell:

Try Nushell and we can learn more from it.
And make arturo better
