Using the new API and other major bug fixes

[guruevi]

Hi,

Due to severe issues with the existing jamf2snipe on large JAMF/Snipe installs, I rewrote most of it using the new JAMF Pro APIs since the JAMF Classic API is being retired.

I think most of the functionality is there. It is more flexible and an order of magnitude faster (5 minutes vs 2.5 hours for 2k assets)

I have the rework here, but I don't want to push it as a PR since the change is huge, feel free to use my branch:

Thanks!
