Feature: Add bookmark

[OshinoShinobu-Chan]

Add a subcommand like zoxide bookmark foo ~/foo/src, so you can use z foo to jump to ~/foo/src. This may solve the problem, where multiple projects all have folder src. You can add different bookmarks for different srcs in different projects, and can jump between them conveniently.

I support this and would be happy to open a PR. This features fits perfectly (IMHO) within the spirit of the project (concise, efficient, and intentional directory switching).

However, I'm hesitant as to whether this is a meaningful solution to the problem you've outlined. There isn't a point in separate bookmarks to solve your problem, since one could just type foo/src and bar/src` separately when they want each one respectively. Of course, they could come up with more concise bookmarks for those src directories which might be convenient.

I'm also not sure as to whether this is a good solution things like #929, although perhaps it could be if users stick to using their src directory aliases even while in the parent directory of a desired src.

I don't like bookmark system.
The database of zoxide should be kept simple.
Bookmark could be done in other tools rather than zoxide.

[azaleacolburn]

How would these other tools integrate with zoxide? Or do you mean a completely separate tool for bookmarking directories? Currently the only dababase change is making it a tuple, which doesn't actually add meaningful complexity in my opinion.

A completely separate tool for bookmarking directories

z foo choose bookmark first: I really doubt this design

[lengyijun]

I guess supporting bookmark requires 1000 loc

• completion for bookmark
• fuzzy select on bookmark (both key and value)

I hope intuitive prs to be merged before: #1027 #1039

* completion for bookmark

* fuzzy select on bookmark (both key and value)

I agree this would become problematic. Could we have the bookmark feature without these additions? What do you think @ajeetdsouza?
