Feature Request: Add insert and remove API to Vector similar to Vec

[White-Green]

First off, thank you for creating such an excellent library!

I would like to propose adding insert and remove methods to the Vector, similar to those available in Vec.
I’ve considered implementing this using the same algorithm as in B+Tree, but this might lead to more expensive index calculations for get and set operations.

What do you think of this approach? If it seems like a good direction, I'm happy to work on a PR.
If you have any other ideas or suggestions, I'd love to hear them!

Thank you!
