Base mod in 1.0.0 [1.21.1] uploaded.

-This versions depends on sable >=1.2.2 and createStuff&Additions >= 2.1.2-

Featuring: 

• JetPack sublevel floor detection
• Grapplin sublevel hooking (very fun tbh)
• Block Picker sublevel interaction (can take and place blocks from/to sublevels from/to main level) -Grapplin item working in offhand (isn't able to create 2 chains at the same time)

Configurable:

• Hide netherite jetpack / exoskeletons from first person view (client config)
• The selection of block entities with 'Block Picker' is disabled, as in some cases block data was lost. (common config).

Fixes to vanilla Stuff&Additions: 

• Grapplin hooking to sublevels crashing the game -Floating blocks crashing the game when colliding with sublevels
• Last S&A update broke tank fueling/filling items wasting x10 of fuel (this isn't a Sable thing but was pissing me off, it will be here until the creator fixes it)
