Refactoring after update

• remove temporary casts and imports

New connector GUI features + #551 fix

• Now in GUI you can see connected block for each direction (also info about block when hovered)
• Connector name is now correctly displayed when reconnecting for other players as well
• Directional name toggle buttons now do not lose state after reopening the interface.
• Not connected direction always disabled
• Direction connected to other connectors and cables is always active
  New GUI Example:
  

Optimisation "ticking" code for all channel types

№	Description	Before	After	Channels
1	Combining simulation and real insertion methods	Doing work twice, simulate then real	Unified method based on pipez one. Still safe but faster	Item channel Fluid channel
2	Cache connector position	Request position every tick for every connector	Stored as new field in cached connectors	All channels
3	Skip processing of full inventories if there are many extractors	Trying to insert to full inventory for every extractor in cycle	If we have more than 2 extractors, we memorize the full inventory and skip it for the next one. We perform this operation when processing the first and middle extractor	Item channel
4	Cache rate for energy channel	Check limit rate every tick for every connector	Stored as new field in cached connectors	Energy channel
5	Check required energy	Iterate over all extractors	Stop the iteration if we have obtained enough energy to fill all consumers	Energy channel
