Structure for re-usability and concurrency

[System-Glitch]

Description

Create a structure and make it implement the slug functions.

Benefits:

• Ability to slug concurrently with different settings (this wasn't possible because of global variables)
• Better re-usability

Drawback:

• Very slightly slower due to map cloning when creating a new Slug structure.

Example usage

s := slug.New()
s.MaxLength = 80
s.Make("Hello world")

Notes

This change is not breaking.

Similar to #41

This patch would support closing argoproj/argo-cd#18369. It's been some time since it was open. Is it worth re-evaluating, or is there an alternate solution?

Hello, I forgot about this. It's been a while! I still think it would be a good addition worth re-evaluating. It should be updated though, as some options are missing from my PR.

Hello, yeah, it would be good to get this functionality. I also see this PR: #41 that attempts the same goal. I see @matrixik as the primary reviewer and feedback provider for the recent PRs. Maybe he could provide some guidance on how to get the ball rolling again. It probably won't make sense to update both PRs.
