feat!: improve flatten: false and rename to structured: true

[brunoimbrizi]

(Re-submitting after the git history snafu on #47)

This PR addresses #46

• remove ../ from dir so dest reliably replaces the first folder in the path on .split('/')[0]
• trim slashes from the path so destDir doesn't end up in the root folder
• update test 'glob with dir': dest should be expected to contain dir when flatten: false

Were those commits made to a protected branch? I don't think I have access to them. When opening the links on github I get the following warning:

⚠ This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

That's after doing:

$ git remote add sapphi-red https://github.com/sapphi-red/vite-plugin-static-copy.git
$ git fetch --all
$ git cherry-pick 82e69bd

fatal: bad revision '82e69bd'

Probably running git apply with these patches will work.

Sorry, it didn't work.

$ git apply 3544728f42e659e76216894111f13c36552668e5.patch

It's my fault for getting rid of pr/47. Would you be okay with me copying the changes and recreating the commits in this PR?

[sapphi-red]

I'm fine with that 👍

[sapphi-red]

Thank you!
