Added dot notation along with appropriate types

[newclarityex]

This fork adds dot notation with working TS support and removes the 'has' function as I felt it was irrelevant.

Thanks a lot for your contribution!
I had one suggestion:
The has function was added since this library was inspired by electron-settings which also exports a has function. This library tries to make switching from electron to tauri easier by providing a similar API that can be migrated to. Could you revert the change?

I'll review the rest of the changes soon.

Oh I didn't realize, I've reverted the has change. Everything else should work mostly the same, only with added dot notation.

Thanks! I won't merge this into main yet. A few things need to be done still:

1. Updating the documentation
2. Dot notation for arrays key1.key2[3] which is allowed in electron-settings. (If it isn't possible, the documentation should be updated appropriately)

I'll create a new branch and merge this PR into it. You can contribute further if you wish or I'll handle this and try to release this ASAP!

Is it possible?

I don't think I'm able to. electron-settings does have that functionality, but I checked and the way it's implemented has incomplete TS support.
