Adding JSDoc comments throughout

[JerrettDavis]

Is your feature request related to a problem? Please describe.
It appears that while there's excellent documentation for the library, very little of the code itself has attached in-code documentation. This often requires me to look directly in the library's code to really understand what a method is doing. Implementing JSDocs throughout would allow IDE code-completion and code-hints to better help other developers.

Describe the solution you'd like
Add JSDocs to all publicly facing methods.

Describe alternatives you've considered
None

Additional context
None

Hey, thanks for the input. Yes, I would love to do this while we want to keep the documentation to the public OidcSecurityService as he provides a facade as entrypoint for the library.

I would like to see this asap, so we can branch from main and do a PR from there. Would you like to help with that?

Thanks

[JerrettDavis]

I'm more than happy to start up a branch and get to documenting. I should be able to get on it here in a few hours after I wrap up my day's work.

Take it easy, no rush. I can definitely review and help you with that. Thanks!
