feat(type): support type-string for timestamp type #815

Closed caicancai closed 10 months ago

I feel like it’s very simple whether timestamp will support it. There may be some problems that I didn’t pay attention to.

Feel free to have a try. It would be more challenging than this one. 😀

Thanks, I'm going to try it, I want to ask about the writing of the optimizer I may not understand very well, is this a rust-specific way of writing.

rw!("inner-join-on-right-empty"; "(join inner ?on ?l (empty ?r))"   => "(empty ?l ?r)"),

It looks very simple
