sor: extra gas calc

[ondreez]

not necessary dispatch with extra gas all the time in router - do it dynamically, based on users position, if no position in MM we dont need to add extra gas

ideal solution:

1. dryrun tx to see if it fails or not on out of gas
2. if success = no extra gas
3. if it fails = wrap it with dispatch

solution no.2:

• estimate gas to determine that accurately - estimate with non 0 gas - the current estimator works as well

solution no.3:

• fix for looping positions
• for 1 supply and 1 borrow position - this doesn't need extra gas
• We have lot of these accounts and those accounts are sending lot of swaps, so using extra gas for each of these is very inefficient
